C6 Z06 brake rotors are 14" front and 13.4" rear. The carbon C6 ZR1 rotors are 15.5" front and 15" rear.

Not a bad price on these used fronts. https://www.corvetteforum.com/forums...nd-rotors.html

Amazing... well done. Were you at Carlisle last year before these latest mods? I feel like I saw your car.

That is correct. Still had the other brakes and tires on at the time. Started this project when I got home from PA

Awesome job. I recall Pumba doing this several years ago with a C5Z and doing a big write up about it. If I recall he is/was an engineer with GM or had someone with him that was. What I remember the most was that he had to redo all the suspension because the knuckles were not strong enough to handle the loads the brakes could exert on them. Not saying you will have an issue but its worth a search over in the C5 part for it.

Yes... he put the latest iteration of uprights on because the caliper mount is way beefier from GM's testing at the Nurburgring. I ran them on my C5 racecar as well. It has nothing to do with braking force generated by the carbon brakes, but with upright flex under hard cornering pushing caliper pistons away from the rotor creating an initially soft pedal.
