It will fit, but if you have the original brake booster, it will need to be modified a bit, as the brace won't fit under the booster.. Makes install a bit more than 10 minutes too, but still works very well. Here's a pic of the brace sitting on my fender showing how much had to be removed to make it work. Still would do it again.

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.

I did a little bit of searching and found that there were two manufacturers of 944 brake boosters, Ate and Girling. I know that I designed the part around an Ate booster, and have test fit on a few cars with that booster. I'm really amazed that you would have that much interference. I know it was a close fit, so I could understand if due to slight variations in body sheet metal, that you may have to trim my bracket slightly,but that picture shows much more than a trim. Sorry you're have such a hard time; please let me know if you figure out a resolution on the booster size question.

Wow. I will look into this more. Sorry for the trouble guys... I intended for this to be a bolt on part with no modifications needed, but apparently that is not the case, at least on some cars or with some boosters.

Let me know if I can help by taking some measurements or something.

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.

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.

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".

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.
