since the offsets are wrong on the 993turbo front rotors, are the GTS,
C2 turbo, S4 offset type hats? and the 993T rotor size?
I'm running this setup with 928MS caliper adapters and dont have any clearance issues between the rotors and ball joints. Are they close, yes, but there are no contact marks or noises and I've driven the car a few thousand miles since doing the brakes. Carl checked them when he installed them and I checked them again a couple months ago.
I have always said if I had the excess money, I would get a custom large ceramic braking system for it. I remember saying I would like to see the glow those things do under heavy breaking and hacker said you would never see that on a street car, well now you do, technically not a "car" buy still impressive F1 like braking glow on these STOCK ceramics
We own the best looking car but the brakes are the Achilles heel, looks and performance. I have a LOT to do before I get to improving the brake situation and only a custom setup up front is the way I would go as I like my spindles.
Going to S4 brakes is a huge improvement and if you choose GTS calipers you have a solution Audi puts on the 360 hp S8 with 400 kg more on the hips and way faster.
S4 are not that much better, BUT GTS Big Reds are! But again that requires a spindle change which is major surgery. I want to find adapters that would allow a bolt on solution of really NEW brakes that not only look good but STOP GOOD>
From memory I believe that S brakes are around 135 ft from 60-0
GTS big reds are 110 ft from 60-0
The Best cars of today are stopping at 90 ft from 60-0 which include the 991 GT3 (which I tried to buy
45+ feet of stopping distance is big. The feel must be great. My departed Ford Fiesta ST did 105 ft 60-0, such confidence in stopping
The current RECORD HOLDER is 86 ft by the Ford Mustang Dark Horse
I wonder how the stopping distance is actually measured. Seems like there is going to be some reaction time involved, which I would think could vary.
On another note, I recently made some adapters for one of our guys to adapt Lexus calipers and Boxster Rotors to the front of his 928. I think there is something about it in this forum fairly recently since that is when I finished up the second set for him.
Edit: I bumped the thread about the adapters I made for Wes.

Jerry you must have read my mind. YOU were one of the guys I was going to mention that could help us out with adapters for some of these new options.
You and some of the guys if any here work with software and 3D printing!
