All GT500's from 07-12 got the carbon fiber clutch packs. So did the '08 bullitt.
These 8.8's are very strong, and the only weak link really is the Ford track-loc.
Give me 10 brand new Shelbys off the show room floor and I'll show you gear whine and incorrect backlash. It's not the 8.8 that's giving up, it's the assembly job from day 1.
Install a proper diff, set it up correctly, and the rest of the stock parts will take you to 10.00 or quicker without a problem.
I agree.
