Picked up a new THirdgen which came with Ronal R15 wheels. Want to swap the wheels on the Iroc (18") for these, but the problem is I have C5 Z06 brakes... WHats the largest Brake I can put under the ROnal R15's I tried searching and pretty much just came up with 1le...

the c5 brakes should fit no problem. Give them a try and see.

It really depends on the caliper but usually the biggest brakes that will fit in a 15" rim are 12" rotors.

I have a 12.2" rotor under my R15's and I have room to spare. I only have that size rotor because I want to be able to use the original GTA crosslace wheels
Well they did not fit... Crap... Time to get a little bit smaller brake and put the Z06s on the 92.
