Quick input - I put these on about 3 weeks ago and have run them at 3 different tracks so far (Limerock, Palmer Motorsports, and Thompson Motorsports) here in the Northeast. Thompson is very very hard on brakes, and the brackets held up great.
I battled brake fade all last year and early this year with my OEM rears (11.8") and it is seeming that going to the bigger rear rotors is helping a lot on my car.
So a total of about 7 hours of track time on them thus far and nothing but good feedback thus far. I inspected following my recent "torture test" at Thompson and there are no indications of cracking or stress in general.
What was your choice for rotors?
