Due to the size of those calipers and the wheel offset required to fit over them, there's not enough room for much more than a 1" lip on the front wheels.
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.

False... we race C5s on stock uprights on slicks no issues. Punbas car was very nicely done, but he didn’t change uprights due to brake torque.
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.
Pumba and I emailed back and forth a few times. My car is more about the show and rarity than race track performance. I do drive my car but I don't want to subject the paint to hard track days. Thanks for the input!
