Clutch Master Firewall Reinforcement **INSTALLED PICS PAGE 3**
3 Attachment(s)
Thought I'd post this up in case any of you high HP 951 guys with heavy clutches need one. I designed this for my v8 swap as a preventative measure (don't have any cracks yet, but I've heard it's just a matter of time).
If you haven't heard of the firewall cracking problem, here's my understanding... some cars (mostly ones with heavier clutches fitted) have developed cracks in the firewall around the clutch master cylinder due to the extra force exerted. I've seen a whole lot of crazy looking solutions to this that look only marginally effective. I wanted something cleaner looking and more of a bolt-on than weld-in. Anyone who's interested in trying one, let me know. I am waiting on the fabricator's quotes right now. Figured I'd start with just a couple first to test fit them in a couple cars I'm working on. They will be laser cut from 13 gauge steel, press broken, welded seams, and then powder coated. I'm guessing they will cost about $150 each in quantity? **UPDATE** Price is $99 + shipping ** The basic idea is that it goes between the firewall and the MC, and the other end wedges up against the very sturdy strut tower. Optionally, a couple holes could be drilled to bolt it to the strut tower or through the wheel well. **UPDATE: After test fitting the prototypes, I do not believe that any drilling into the strut tower or wheel well will be necessary. The bracket feels very secure in its position against the strut tower. I plan to install it with just a layer of silicone between the bracket and the strut tower to prevent any marring of the surface from vibration during driving.** |
Alan, count me in for one. Firewall reinforcement is on my list of things to do.
Which clutch are you running on your LS swap? I have the Spec Stage 2, hope its not too heavy! |
Cool, thanks! Will keep you posted.
Same here, Spec stage 2. It's a lot heavier than the stock 951 clutch, but I still think it's the best choice. Make sure you're using a bigger MC (like a Tilton 7/8") or it may not release completely. |
could you make the full firewall reinforcement plate?
|
A Honda Civic clutch is heavier than the stock 951 clutch! :)
Im using Wilwood part # 260-6088 which is .7" bore with a 1.4" stroke. We figured the smaller bore should make the pedal feel lighter. My friend and i bench tested it with my clutch on his LS3 and it seemed to have plenty of travel to release the clutch fully. Did not get a chance to test it before i left, still had to get the NPT to AN fitting for the quick disconnect hose. |

I think the firewall cracking problem has more to do with the heavier clutches and fast clutch actuation that we all do during races and DE's. And I think a bracket like this one does a better job at supporting the clutch MC than a flat plate on the firewall. You gonna buy those headlight brackets I sent you? ;) |
I will probably be in for one too. How does it mount to the strut tower? You said wedge but is that sufficient strength and "grip" wise?
Only suggestion is that (and it might already have one, cant tell from the angle of the shot) it needs at least one drain hole or itll be a bucket for brake fluid. |

I was going to look at making a reinforcement plate that goes on the inside of the firewall somehow since my dash is currently out and ill likely take some of the wiring out and the steering column out for other work. |

Theres several of those available but the issue with them from my reading is they dont seem to keep the clutch master at the same angle as stock, so it wears out faster. I could be completely wrong but thats what I have read.

Would this if you have a LS swap?

When I used one of those big flat firewall reinforcement plates, the clutch pedal effort was not consistent, like it was binding or something. I figured it was probably due to the angle, but won't know for sure until I install this new one that keeps the proper angle. |

Hey Reno... not sure if this is what you're asking, but yes this bracket works with an LS swap just as well as 4 cyl 944/951. It really depends on what MC you're using though. I know it fits with a Tilton 75 series (which I use) and the stock 944/951 MC. Not sure about Wilwood, etc. If someone can send me a part number for a typical Wilwood MC that LS swap guys use, I'll look into that.

Hey Alan,
Sounds like a nice idea. I am braced to the fender using an L bracket, but doubling up might not be such a bad idea. I'm in for one. I might forget about the post, so please PM me when they are ready! |

Alan: Did you get the unit pricing? I have an interest. Thanks, Mike
|
Good idea. A threaded adjuster bar between the strut tower and firewall would account for differences between chassis from prior wrecks or differences in cars. IIRC, Koklen made one that attached to the strut mounting bolts on top of the strut tower.

They will be in the neighborhood of $100 each; more or less depending on the qty I order. So far it looks like only about 3 or 4 interested? I guess I probably need to market them more to the v8 guys.
Market them to anyone with a heavy clutch, like a KEP Stage 2. |
I would most likely be interested in one for my 968....I would think it would fit.....
|
Add me to the list as well.
|
Now we're talking! Thanks for all the interest! I'm still waiting on the prototypes to be made. Hopefully will have them soon and then will post pics.

Brilliant Idea!
I had a stiff clutch on my 968, and it was causing the firewall to flex, until is started to CRACK! The flexing was making it harder and harder to change gears, and eventually the crack created an opening from the engine bay right to my left foot!! I had to take everything out and weld a triangle in and fill the crack.. what a HUGE pain in the posterior!! I HIGHLY recommend a bracket like this to anyone with a stiffer than OEM clutch! |
Add me to the list

Nice product. Couple of questions:
- will the brace scratch up the shock tower? Can you make a provision so the brace mounts to the 4 bolts on top of the shock tower, thus preventing the brace from rubbing directly against the shock tower? - will adjustment to the clutch pedal linkage be necessary once the brace is installed? I'm assuming the clutch master is removed, the brace installed, and then the clutch master reinstalled? Thanks |

Bolting to the top of the shock tower was my original concept. The problem is you end up needing a much more complicated assembly of brackets to do that, and in the end I don't think it's as effective structurally because you need so many bends in the metal. It has been done (if you search here and 944 v8 swap forums you will find lots of different versions of this concept), but I just prefer the simple approach.

Thanks Also, as for MC removal, I am hoping that the MC will be able to remain connected to the pedal linkage and hydraulic lines during installation. Hopefully, just remove the 2 nuts, push the clutch pedal in to force the MC out from the firewall, and slide my bracket in behind in, then put the MC back. Won't know for sure until I get the prototypes, but that's the plan. Thanks for you questions and interest. |

OK, finally got the prototype brackets made and test fit on a couple cars. Fitment is excellent. I made a couple of minor tweaks to the design to make installation easier. On cars with the vacuum brake booster, it will need to be removed or at least pulled out of the firewall and slid over about an inch in order to install this bracket. V8 cars don't have the vacuum booster, so it should be very easy to install for them.
Here are some pics of the prototypes. Note that the production units will be professionally welded and powder coated, so they will look at bit nicer. The first 2 pics show a bracket installed with the OE 944 clutch master. The vacuum booster is not shown for clarity, but I did test fit it. The last few pics show the same bracket (before welded or painted) with a Tilton 7/8" clutch master installed. PM me if you would like one... price is $99 + shipping, in hopes that most everyone who expressed interest will follow through with an order (I need to order a batch of 20 to get the cost down enough to make this worth my while). Thanks! |

A part a good friend of mine made off a pattern provided by another lister. It had to be slightly modified from the original design. Also a warning to everyone running very stiff Pressure plates, make sure when you install a firewall flex plate that you verify the angle of the clevis rod doesnt change too drastically do the the added thickness, the change in the angle of the applied forced can easily snap the clevis rod. Some modification to the rod may be required to return its angle against the master cylinder piston closer to stock.

Hey Doug,
Yeah, I had something like that plate in my v8 swap car for a couple years. It throws off the angle of the master cylinder relative to the pedal linkage. That's exactly why I designed the bracket shown above... see previous posts discussing the pros and cons of firewall plates in detail.

Just a thought, would it not be better to mount it behind the cylinder?
Firewall | Clutch Master | Brace | Nut If my memory serves, there is a gasket between the clutch master and the firewall and it looks like with the bracket between the firewall and the clutch master there is a gap now? |

Did you ever confirm if this would work for a 968?

8 of the 10 are already spoken for, so if you want one of the first batch, pm me and I'll send you my paypal info. Thanks, Alan |
Alan-
When do you expect that they will be ready? Thanks! Paul |
I still would like one. Mike

I'll take one if you have any left. Looks like a nice design and its worth a try!

I think I have an "audipages" email address for you, and that isn't working with my yahoo email for some reason. Anyway, the update is that the first batch was made incorrectly, I received a new batch that was made right, and now they are being powder coated. Should have been done by now, I know. The next batch I do will be pre-made before I collect any payments! You guys have all been extremely patient, and I really appreciate that. |

Finally... will be boxing them up tonight and shipping out tomorrow! Thanks again everyone for your patience.
|
All 10 of the first batch have been shipped out. If you need any installation help, please don't hesitate to email or pm me. Since these brackets are designed to work in a variety of applications (V8, Turbo, and NA cars, as well as various clutch master cylinders) I have not been able to put together detailed instructions yet.
|
I received mine today....thanks Alan! I'm going to do a timing belt service in April, I will consider installing it then....need to inspect my existing condition first. Need to look at what needs to be done....plus I need to do a close inspection of the brakes and change the fluid for a track day in May so the timing will most likely be perfect.
|
Received today...nice piece
Thanks |
Hey Alan, if/when you do a second run, please put me on the list for one.
|
Add ,me to the list too.
|
dmcampbell, Dare, and blitz951... thanks for your interest. I'd like to see how things go with the first batch installs and feedback. I don't foresee any problems, but you just don't know with a new design until it's out in the field...
With that said, can you guys all wait a little while? I'm thinking maybe a couple months. |
No problem just let me know when your ready.
Thanks |
No worries. Sounds like a good idea.

Clutch master cylinder reinforcement plate
hi. How do I order one of these clutch reinforcements from you?
Thanks, Bill |

Thanks, Bill I was hoping to get some feedback from the first run after people had time to install them. No feedback yet... I did, however, get a chance to install one myself on a 951 with a vacuum brake booster on it. It fit really well on that car. The only downside is that it is impossible to install with the brake booster in place. So, it will add a good bit of time to the install on cars that still have vacuum brake booster. On v8 cars (which typically go to hydroboost or manual / dual master cylinder setups) there is a lot more room to install the bracket, so it is fairly painless. On my car with an LS1 and BMW hydroboost, for instance, it literally can be installed in 10 minutes. All that being said, if you and at least a few others are still interested in having me make another batch, I am willing to go ahead. Can't wait for feedback forever! I'll put out messages to those who expressed interest, and then get them made. Once they're made and ready to ship, I'll contact you for payment. My guess is it will take a few weeks to get them made and ready to ship. It will be $105 shipped, and I accept paypal if that works for you. Let me know if you still want one. Thanks, Alan |
Finally have 4 people interested in these brackets, so I'm going to get a batch of 10 made now!
PM me if you're interested and I'll put you down for one. I'll wait on taking payments until they are ready to ship. It will probably be a few weeks due to the lead times for laser cutting, welding, and powder coating. |
I'm thinking of doing a LSx swap in my '86 but have tons more of research to do first (it's been a couple of years since I've had any interest in my 951 and it has sat for two years in the garage). I'd like to get one of these, regardless, since I'm upgrading my clutch.
PM inbound. |
I am interested in one too. Thanks!
|
Nice design!
Do you plan to make one in aluminum? I'll take one anyway. Thanks! |
Alan, you can add another one for Alain here in Montreal.
I will take car of the payment and shipping for both of us. I will use a US address. Thanks |
Wow, nice... Lot's of interest all of the sudden. I put in the order for the laser cutter for a batch of 10. Looks like all 10 are spoken for, but let me know if you would like to be put on the standby list in case some drop out (or I can make another batch, of course).

Guys, I received the batch of 10 brackets this morning from the fabricator. Next is powder coating. Should be ready to ship them early next week. I'll send PM's to the first 10 who already expressed interest to collect payment, and as folks drop out of line I'll contact everyone else in order.
Thanks, Alan |
Payment sent, thanks!!!
|
Money sent, as agreed, for 2 brackets.
Thanks! |
Paypal sent! Thanks, I appreciate it.
|
Money sent.

Any chance you could post measurements or even designs for this?
I think I'd prefer having the plate on the outside of the clutch housing instead of in between. I've made a (simpler) bracket before that does that and that worked fine. Thanks |

Jannes, yes I can share some dimensions with you. Let me know what you need. If you have access to 3D CAD program, I could send a model that you can get dimensions from. I'm not going to send out my bracket design (too much time invested in getting it right), but I'll send the plane of the MC mount, locations of mounting studs, and plane of the strut tower face. Anything else, just let me know.
I have one 931 project car with a torn firewall, but we still need to take it apart to have a good look. Only then could we hope to make measurements ourselves. Do you know if your bracket also fits 924 / 931 ? It really looks like the best solutions I've seen so far. My 968 daily driver does not seem to have this problem, but I would like something preventative. In that car I don't feel like taking everything (intake, brakebooster etc.) off though. So a simplet bracket that goes over the cilinder instead of in between would be preferable. Thanks |
Just arrived! Thank you sir!
Edit: Just installed, great fit and finish. Very happy! Maybe I won't rip my clutch master off the firewall this time ;) |

Thank you Alan! I was able to convert the file and open it. Very cool!
I was mostly looking for the distance from the firewall to the suspension tower and the angles involved. Are those still intact in the image you sent even though you left the middle parts out? |

Do you have any left over? If not do you plan on another production run? If so could you please add me to the waiting list.
|
I would be interested in one as well. Can you please let us know the availability.
|
Can I get one that is not powder coated? I have a bunch of parts I am taking to the powder coater and I'd include this so it matches the rest on my parts.

Guys,
I found another shop to make these brackets. Sorry to keep you all waiting so long, but I was hoping that my usual shop would get their laser cutter back up and running by now and it hasn't happened yet. For those who are still interested, what do you think of using stainless steel in lieu of powder coated regular steel? I know azbanks wants his uncoated, so as long as noone objects, I'll get this batch made out of 304 SS. They will be stronger than regular "hot-rolled" steel, and you can still paint them if you would like to match them to your engine bay. Thanks! |
I'd be interested
|
I went ahead with the 304 SS.
|
Please put me down for 1.
|
Just checking in after I've had mine for a while....
I still love it. No torn firewall like my old car. Well made, holding up great. Awesome investment. A must have piece for anyone running a heavy duty clutch setup. I'm running a spec stage 2+ clutch setup, 6 puck on one side full face on the other....10.5" disc. Stiff pressure plate. Happily putting on worry free miles! Thanks again. |
I am interested as well.
|
I'm interested!
|
I'm also interested!!
Count me in for one. |
Also interested please.
|
Guys, I'm going nuts here. I just received 10 of the brackets from a new supplier, and they are not quite right. They used thicker gauge metal (stainless steel), and they MIG welded them rather than TIG. The main problem is, the dimensions and angles are a little off from my design. They may very well work, but I can't guarantee them. And the MIG welds are not corrosion resistant like a stainless wire TIG weld would be.
So, I hate to keep people waiting, but I'm going to have to go back to my original supplier (their laser cutter is back up and running now). In the meantime, I'm going to offer the 10 brackets I have sitting here for half price and (as usual) a full refund if it doesn't work for you. So $50 plus shipping for these 10 only. Pm me if you're interested in one of these and I'll provide my PayPal address. Sorry again to everyone who has waited for so long. |
Can you show any side by side pics of the originals vs the new ones? How far off from spec are the new ones?
I'm not worried about corrosion since I'm going to powder coat it and I live in Arizona. The only salt we get around here is on our margaritas. :cheers: |

Anyone heard from vt951 recently? |

OK guys, I know it has been a very long time and I apologize for that. But, I finally have the proper brackets made and available to sell again.
There is a plus side to the long wait... I went ahead and got 20 of them this time. I will pass on the savings of making 20 at a time... these are $89 plus shipping instead of $99. If anyone is still interested in buying one, please send me a PM. |
Pm send for me!

Product received this day and of very beautiful invoice.
Thanks Alan! |

Bolting to the top of the shock tower was my original concept. The problem is you end up needing a much more complicated assembly of brackets to do that, and in the end I don't think it's as effective structurally because you need so many bends in the metal. It has been done (if you search here and 944 v8 swap forums you will find lots of different versions of this concept), but I just prefer the simple approach. I don't really think linkage adjustment will be necessary. You are correct that my bracket installs behind the MC, but it is only 0.090" thick. I don't think that takes the clutch pedal linkage out of it's range of travel, but it will put the pedal a bit further from you. I doubt it will be a very noticeable difference, but maybe I'm ham-footed. :-) Also, as for MC removal, I am hoping that the MC will be able to remain connected to the pedal linkage and hydraulic lines during installation. Hopefully, just remove the 2 nuts, push the clutch pedal in to force the MC out from the firewall, and slide my bracket in behind in, then put the MC back. Won't know for sure until I get the prototypes, but that's the plan. Thanks for you questions and interest. |

If you want to prevent scratches to your paint on your strut tower, the coating I would use is just a clear silicone caulk. Just a small dab will lubricate the strut tower surface as the bracket slides in. When the silicone sets up, it will also keep it from moving at all when you're driving (over bumps, etc.). |
Interested in purchasing a firewall bracket. Please tell me how to arrange payment and shipping.

Are there two different diameter brake boosters for the 944? My car is non-ABS and has an ATE booster. I am having a very tough time getting the brace to clear. FWIW the booster is about 9.5" OD. :confused:

I had the same issue on my non-ABS '86 turbo. Definitely an ATE booster. No idea why the clearance would be any different.

Here's a picture of the final result. It's obviously lost a ton of its stiffness but in compression (which it mostly is) I think it's still stiff enough to do the job.
If my brake booster was ~1" less in diameter it would have probably fit without issue. I replaced the booster since I was in there, and compared new vs. old (ATE, non-ABS), and they were identical in size. In Dare's pic, it looks like his interference was about an inch forward of mine (?). I don't see a way to actually run a bracket in a straight shot to the strut tower with the size of the booster being what it is (at least on my car). It would need to run down at a decent angle to clear. :confused: |
I wonder if its a difference in the seam that runs around the circumference of the booster. You can sort of see in this picture that if the seem weren't there the brace would have fit with its original dimensions.
https://cimg9.ibsrv.net/gimg/rennlis...bdbf270b2d.jpg |
On my booster the seam appears to be more toward the firewall. Your seam appears to be where the the threads are on the clutch cylinder and mine is behind the threads. Assuming the clutch cylinders are the same length then your seam is more toward the front of the car than mine.

Just another data point... I found some of the original test fitment pics for the first batch of brackets on two cars: the red one is my ls1 car, the dirty white one is a chump car I'm building. It was close, but it did fit on both of my cars with an OE 944 vacuum booster. The OD of this booster (which I still have on the shelf) is a little over 9.5".
|
Just bought a 968 and would like to know if that will fit without modification I don,t know which booster I got
Thanks Marc |
Sorry, but I really don't know. I don't intend to sell these brackets for use on cars that have vacuum boosters (too many fitment issues). Pretty much any car with a v8 swap should fit fine, though.

944S2 Master Cylinder Firewall Reinforcement
Hello,
My mechanic replaced my clutch and I asked him to check the MC for softness. He tells my the firewall is cracked/moving with the MC. Found your bracket online and guess I need to put one on. Do you have available and how to purchase? Thanks, John from LaPlata, MD |

Do you have available and how to purchase? Thanks, John from LaPlata, MD I do not have any more in stock. I'm planning to make a new version that will not have the interference issues detailed on the previous page and will be easier to install. The current design still should work great for anyone who has a v8 (or v6) swap and removed the vacuum booster, but I'm assuming you still have the Porsche engine in there. I'll post here when I have a new design ready. Alan |
No worries. Thanks. I got one from someone in MA who bought one from you earlier and didn't use it. Came brand new to me. Saved lots of time and frustration by reviewing this thread because yes, the brake booster on my 1990 944 S2 was certainly in the way. I used the grinder to make room on the brace to go around the booster and it went on without too much difficulty. Then the real fun started in trying massage it place. By nudging the brake booster a little to the centerline of the car I was able to get the bracket to slide around the edge of the strut tower and lock in place. The bolt holes were a little too wide on mine so I used a hammer to slightly pinch together the u-shaped slot where the MC sits against the firewall. Viola! Then I spent the better part of two hours trying to get the nuts seated back on the two MC bolts. With the bracket in place, the bolts barely reached through the MC holes and didn't leave enough threads exposed to get the nut to purchase. More applied pressure to the MC housing toward the firewall and got the inner nut to catch. I used a universal joint socket adapter and filled the socket with paper and used electrical tape to make sure the nut hit the bolt first and didn't slide back into the socket and didn't fall out. Lost two somewhere down the rabbit hole. Once the inner bolt seated, I used leverage on the MC away from the center of the car to get the outer bolt to poke through. That one went on in seconds. Two year clutch problem solved. Thanks.
|
John, what an adventure! Glad it worked out for you, though.
|
Hi, do you have any more anticipated production of these?
I might need to do clutch cylinders sometime soon and this is a good "while you're in there". Maybe one that you could send me, and I could forget it for 3 years and send it back? :) |
What are you do for the extra space? should be a couple of mm space between the master o-ring and the firewall with the bracket in place.
|
944online has some, I believe.

How does this compare to the one <only944> sells?

Just by looks the "plate" just reinforces the firewall to stop/lessen flexing.
Whereas the "brace" would entirely prevent the firewall behind the MC from flexing making sure all the "pedal motion" is being put to use actuating the clutch. I would think the brace is a better solution and the plate is a "repair part" for an already cracked/weakened wall. |

If you can get the fitment issues sorted, have you approached any of the big 4 online sellers about carrying these for you? Pull a Josh and have someone else worry about distribution and support?

Am I correct in my understanding that the slight fitment issues relate to the turbo cars only? Seems the V8 guys have reported no trouble?

LOL, dude, drill a shallow divot in the end of the master cylinder as a locator, make up a small bracket that bolts to anything solid like the side of the strut tower with a threaded adjustment bolt & lock nuts and rounded tip to fit in your master divot.

I am familiar with that type of brake MC brace, I have one for my Subaru... :) You'd have to have a pretty split firewall for this to not help the clutch too. I'm down though...., made a custom one off doubling plate for clutch master on a 968 once. Just take it all apart, it'll be obvious what you need to do once you are looking at it head on. T |
I see what you're saying...funny as I had thought about making that type of brace for my 944 too.
I just noticed the other day that my clutch MC moves visibly when the pedal is pushed, and I'm going to be swapping it out in a few days so "while I'm in there"... |

It's scary how much the FW flexes if you get somebody to just go mash hard on the brakes (like in a race condition) even when the FW is perfectly intact with zero issues. T |
What a coincidence, I just finished installing the Only944 Firewall brace on my car yesterday.
https://www.only944.com/partscatalog...firewallbrace/ My firewall cracked a couple months ago. The telltale sign was the clutch engagement point kept moving lower and lower, it got to the point where it was difficult to shift. I've been using the same clutch for 2 years and it always engaged right off the floor. Now that the firewall brace is installed the engagement point has come up higher. It's firm enough for me to adjust the engagement point where I want it, plus I can adjust the resting position a little lower for better pedal feel. Yes the brake pedal feels firmer, too. The instructions for the firewall brace are good, but here's a few tips- I replaced some of the hardware in the kit with flanged bolts to spread the load over a larger surface area. I also upgraded the stock brake booster mounting nuts to flange head nuts with fender washers, again, to spread the load over a larger area. Also, it can be difficult to install some of the bolts under the dash, especially when a bolt needs to have two washers stacked on it, so use something sticky like Teflon paste and glue the washers to the bolt. Then they won't fall off. I'm very happy to have my car back on the road! |

New Design for Cars with Vacuum Brake Booster
Here's what I'm working on to improve fitment around the stock brake booster and (hopefully) allow installation without removing the booster. Next I'm going to build a prototype and test the fitment and installation. Hoping to have a batch made soon!
https://cimg4.ibsrv.net/gimg/rennlis...50ed497d12.png And here's a comparison of the new one to the "V8" version: https://cimg5.ibsrv.net/gimg/rennlis...0b1bb375af.png |
Awesome being able to potentially install the brace without removing the booster.
|
Finally got the new prototype in and the fitment is great. I am ready to have a batch of these made, but I’d like to gauge interest so I know how many to order. Please pm me and I’ll provide payment details. Also, I’m considering having them made out of stainless steel, with TIG welded seams. They might be slightly more expensive, though (guessing about $105). Any feedback would be appreciated. i initially tried test fitting on a car that had the brake booster, and although it does appear to be possible to get it in there without removing the booster, there is just too much other stuff in the way (wire harness, evap hoses, a/c lines, brake lines, etc.). So I think the brake booster will be the easiest thing to remove in order to install this brace, unless you have a race car with most of that stuff deleted. Thanks guys for your continued interest in this, and for your patience! https://cimg5.ibsrv.net/gimg/rennlis...998f8c759.jpeg |

Hi. Has been a long time since my last visit to Rennlist forums. Nevertheless I want to share my experience and repair process with the dreaded firewall cracks. My car is a Porsche 968 Turbo. I have installed a Specs clutch kit with fairly aggressive pressure plate. Unfortunately I dint pay attention to the stories of firewall cracks until it happened to me. I was looking for an effective and elegant solution to solve the problem once and for all and in the end this what I did:
1. The cracks were welded. In my case there two cracks, one that runs across the joint between the firewall and fender wall and another that runs to the Steering wheel column. 2. Welding's were cleaned and painted with a good quality primer and paint. 3. I purchased the Only944 firewall plate and installed it. I used longer bolts in some areas to be able to install a locknuts to prevent loosening of the bolts with time. This required some modification to the Brake booster base. 4. To ensure that there is no flex or at least a minimum flex of the firewall I fabricated an L shaped bracket and welded it to the Firewall plate and fenderwall. 5. Weldings were cleaned and painted at the top and under the fenderwall. To this time it is worked flawlessly and is barely noticeable. It was a fairly complex and time consuming process but I want to be sure I will never look back at this problem again. https://cimg7.ibsrv.net/gimg/rennlis...bc01adf911.jpg https://cimg2.ibsrv.net/gimg/rennlis...0924ad8e07.jpg https://cimg4.ibsrv.net/gimg/rennlis...f31b1f7dd1.jpg https://cimg5.ibsrv.net/gimg/rennlis...0ff89f6a21.jpg https://cimg6.ibsrv.net/gimg/rennlis...df908748e6.jpg https://cimg0.ibsrv.net/gimg/rennlis...0344b5ba0d.jpg https://cimg4.ibsrv.net/gimg/rennlis...1528384d2b.jpg |
I am in for one. Let me know how and when to pay.
|
Still avaliable ? I need one.
|
So far, 6 people have pre-ordered (thank you!). And it looks like possibly crazyz007 and ealoken will be in. So, I'm about to place an order for either 10 or 20 of them with the metal fabricator... I'm leaning toward ordering 20 since there is a setup fee for each batch, but don't want to sit on an extra 10 if nobody needs them, so... Anyone else need one of these?
|
I may be interested in the new model, but I would like it in stainless steel, is it possible?

Got mine in the mail today, real nice looking piece. Looking forward to putting it together with a new master when the garage warms up a bit.
|
Cool product - I'll take one too
|
Got mine yesterday. Looks Fantastic installed today with new master clutch cylinder, DID NOT have to take of the brake booster off to install on my 968. I did have to file a little bit off the bolt hole on Left side "hole farthest from brake booster" to make the turn and fit.
https://cimg2.ibsrv.net/gimg/rennlis...f19418bacb.jpg https://cimg3.ibsrv.net/gimg/rennlis...b6461ca648.jpg |
Thanks, that’s great to hear you got it in without removing the booster. |
Can I get one too ? I would like to order one.
|
Hello, I'm interested in one as well for a stock '90 944S2. Thanks!
|
Finally installed mine today. Like RichardK I also had to use a round file to slightly increase the bracket hole on the furthest from the brake booster side for my 87 951. Lengthwise fit was great against the strut tower and I was able to keep the booster in place. As a note the bracket is about 2.5mm thick so just add that additional length to the normal 147mm (LHD drive) + 3mm (firewall thickness) to get the ideal clevis/stop nut location.

Steven, pm replied.
I am getting another run of these made. I might get some of them in stainless steel, in addition to the standard black powder coat. So far, I only have one person requesting stainless, though. Does anyone else prefer stainless? |
If you make them they will sell. Yes we all want stainless as an option. Just because you don’t get an instant response from everyone doesn’t mean they won’t sell. You got a good product going on and they will sell. I plan on buying at least three more in the future. Make a run of 20 stainless and 20 regular and maybe even 10 assorted Porsche exterior colors to match the engine bays? People like options, the more options the more clientele you draw. I’ll let you know when I can afford the next one. Just keep up the good work. |

That's not really a bad idea at all. Lart, or LR, would have both been great choices to be the go-to V8 swap parts guys all along. No knock on [Kent Marr] (also a stand up character), who took over for Eric Hill when he decided he wanted nothing to do with being a fabricator & re-seller.

Lart would totally know the answer to this question. He loves LS swapped 951’s. Did I write that right? .
In fact i've never met the dude. You have to believe.... He'll never cross over to the dark side. :icon107: |
Hello all,
Just got around to fitting this brace and wanted to know the steps involved. Any pointers would be appreciated. The car is a 1990 944S2. Thanks! |
Does anyone know if these are these still being offered by the OP?

I finally got around to installing mine, I have to say it is a work of art.

Is this something that should be done to a non-racecar but hard driven street car? As preventive maintenance?
That way, you can use stronger clutches if OEM become NLA. -Yogii AKA 968 Novice |
I was about to install one on a hard driven street car but I sold the car first. If anyone wants a new version for cheaper than what is online, please PM me. Mine is black powder coated (no longer available).

This is IMO a must have for anyone who cannot proceed to fix their firewall other than with a drop-in part. |
I am selling one of these for a fraction of the new price if anyone wants one: https://www.ebay.com/itm/295948206842
