13" C4 HD with rear GTA 16" rims!
13" C4 HD with rear GTA 16" rims!
I couldn't find that someone tried this combination, so I need to ask
I would like to put my rear GTA 16" rims to front with 13" C4 HD brakes and adequate spacers.
I saw that IROC 16" will fit this brakes, so what's the problem with rear GTA rims on front, with spacers off course?

Won't fit, IROCs will, lace wheels won't.
these are the only 2 pics I have that show how close they are.

Does anybody know what's the problem with GTA rims and is there any kind of possibility to put C4HD or C5 front rotors? Maybe to shave rim or caliper a little

the problem is the ID of the wheels is much smaller than the others. You can use the 1le brakes, or flynbye (ebmiller) has some wilwood kits that fit.
