I know that the RA6GTO.com website lists Z06 calipers for the GTO. I work for a parts store and I might be able to get my hands on a set, but my question is would I have to get a custom mounting bracket for the caliper? and would I need a bigger/smaller/different rotor? I could probably contact BAER and/or look up a custom rotor, but I'm just wondering how easy a mod this would be.
Only asking cause the Z06 has 6 pistons calipers up front and 4 piston rears.. sounds like a nice grip to me

Might help on the 163-0 run...
I think some of the more serious track guys might appreciate this info..
