Would you like to test a new version I'm working on for cars that have the vacuum brake booster and OE clutch master cylinder? I don't have them made yet, so it will be a little while.
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!
And here's a comparison of the new one to the "V8" version:
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!
Sorry, looks like the first batch will be black powder coated steel rather than stainless. Let me know if you're still interested; I'll send you a pm with payment details.
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.
