Yes, Louie, thanks. Perfect.

 

These can be used with pre S4 bumper covers with some extra work. The S4 bumper cover comes around forward to the wheel cutout on the bottom. The pre S4 has metal all the way to the bottom behind the rear wheel. You would need to retain the bottom portion of your existing metal rear fender to take the place of the wrap around S4 bumper cover. Bend a flange on the top edge to mate with the attachment flange on these. Alternatively, Cut the attachment flange off of these fenders and leave a 1.5" - 2" overlap of your rear fender at the bottom. Bond them together the same as on the rest of the perimiter and blend them in for a seamless joint. I believe I'd do it that way. If you have a pre S4 and an S4 sitting next to each other, you can see how it would work. Not difficult. Just different.

The wheel openings can be cut out, or glassed in, to be whatever shape you desire. The cutout length was constrained by the existing bumper cover at the rear, and rocker panel cover in front. To bring the wheel cutout in closer to the front and rear of the wheel would have meant to modify the bumper and rocker panels. The goal of these was to have a nice looking alternative to existing rear quarters without costing a huge amount of $$ and endless mods and without straying too far from the stock look. The wheel cutout shape is closer to the GTS than S4/GT.

I wrote some installation instructions and posted them here.

That may answer some of your questions too.

 

If you've not seen Professor Ott's rear end, you should review this thread.

If you have expertise on this topic and can help me with the following I’d appreciate it:

Does anyone have additional pics of these flares installed? The links in many of these previous posts (like post #88) are not working for me. If anyone has pics of Mr. Ott’s car or other cars that would be great.

I read that the installation requires creation of fender liners. Can anyone who has done that describe what that entails?

In post 107 there is reference and link to installation instructions, but that link is not working for me. If anyone has a copy could you please post or send?

It would be great to know how many hours this "should" take a qualified shop to complete, if anyone has experience.

If anyone knows a good shop that has successfully done this installation, could you please advise? I am located in Northern Illinois, for reference.

Thanks!

 

Morgans,
Have you tried contacting Louie directly?
I have a set on my race car. No liners.
I don't recall how many hours I put in to cut, attach and blend in the flares, but is was significant.

 

Rob Edwards IIRC has a set installed, and is very active here.

 

Hi John, no I haven't tried to contact him directly and it seems his website is down. Do you have any pics in addition to your avatar you can post of the flares on your race car? How wide are your wheels / tires?
Thanks

 

Here are a couple of pics of the flares on Anderson's Zombie- They're not Ott flares, they're just the rear S4 quarters, flared- apparently the fabricator came over and hammered them out by hand. Note the non-involvement of the fuel filler door.

 

Wow... that's actually amazing that someone can hammer out the stock 1/4 panels and create a flare like that. Are you 100% sure that's what we're looking at? If so, I'm beyond impressed!! I'd think that the panel would need to be removed at the very least.

Can we get more pictures of the process?

How much would on-car fabrication work like that cost?

 

Since I watched him do it at my office I can attest to how it happened. I had removed all the undercoat prior to him showing up but he did both sides in about I hour. It was quite impressive. He has since done several other 928's but I don't know what he charged for them. My car was somewhat down and dirty since it was for a race car but I've seen his work at Pebble beach. He's quite talented.

 

Hi Morgans,
I saw your post on this subject this morning. I noticed that my web site is gone?? I don't know why yet. I've tried contacting the hosting service, but no answer to phone calls or email. I may be down the tubes with it. The site does exist on one of the web archive services. I may be able to extract enough to re-create it somewhere.

Anyway, what can I help you with now? I have the install instructions and lots of pictures. Let me know what your email is and I will try to help. I do have a couple sets of fenders still hanging on the wall. My last customer was in Louisiana.

Louie

 

Hi Louie,
Thank you for your response. I found your fenders to be stunning works of art when I first saw photos of them on Rennlist, which must have been at least 10 years ago now. I recently (finally) bought a set that Rob Roy put up for sale about a week ago. If you could post the installation instructions and any photos you have of them installed I would be grateful. I am not skilled mechanically, so I'll have to find a shop to do the work, any thoughts you may have for me on identifying a good shop (Midwest) and how to talk to them about this project (required hours, pitfalls, etc.) would be appreciated. Finally, my current rear tires are 295s on 18" wheels, do you think they'll appear too narrow?
Thanks very much!

 

I'm running 295's with a 10.5" x 59mm offset with no fender rolling. With a better offset, I think 315's can fit within the stock fender/quarter.

With that said, I'd think that with Louie's flares, 295's would look too small, even if using spacers as they'd appear too narrow from the rear.

 

I agree with Swaybar that I’ll need wider wheels / tires for the fender flares.

I happened to see the following advertisement on Rennlist yesterday:
https://rennlist.com/forums/for-sale...ed-wheels.html

Here is some detail from the ad and also from my communications with the seller:

- Wheels are 18x10 and 18x12.5”
- Seller goes by MJSpeed on Rennlist and is with MCK Engineering in Florida.
- When I requested the offsets the seller said he didn’t know because they are custom wheels with an offset to fit any 997 widebody.
- In the ad he specifies 997 C4S/Turbo/GT3RS (Wide-body) as examples of the cars the wheels are meant to fit.
- He told me had had identified Michelin Supersport as street tires that should fit in the wheels in following sizes: 275/35-18 and 285/30-18 for the front and 335/30-18 for the rear.

I found this fitment guide online in hopes of cross referencing the offsets from the 997 wide body to our 928 required offsets:

http://www.alloywheelsdirect.net/inf..._chart/porsche

The chart shows varying offsets for these widebody 997s, some of which are OK for 928s (as high as ET57 in front and ET67 in rear) but others not (as low as ET47 and ET48 respectively). Also the chart shows what I assume are stock 997 wheels which are smaller in width than the ones I’m looking at, so perhaps this is not even a useful resource for this exercise.

Lastly, even if the offsets were good, it looks like the front wheels would need a tire that could be too wide for my 89GT, although I’m not sure how wide I can go upfront without modification nor if I could simply use a more narrow tire on a 10” wide wheel.

I had pretty much decided to pass on this due to the ambiguity but then decided I’d throw it out to you guys in case anyone had thoughts that would help.

Thanks.
