Thread: GXP Rotors with C5 calipers?

so the grand prix gxp rotor measures 12.7". the rotors for the c5 corvette measure 12.8". So with C5 BRACKETS, and calipers, could i run the gxp rotors? i cant run the corvette rotors for obvious reasons since the bolt pattern is different. unless the "offset" of how the gxp rotor sits on the hub is different. anyone know or try this?

I ran F-body rotors with mine. Not sure on GXP

f-body rotors are 11.9" though.

Theres already a brake thread on here.

the bolt pattern may be different, but the holes in the rotors are larger then the stud, so theres lots of play, since f bodys do fit the 115X5 we have, the c5 rotor should fit as well. if its still the same lug pattern as the f body.

Will not happen with C5 caliper brackets, they will only allow for the 12" rotors, unless you do some custom brackets, but there are two things that come to mind if you do that. 1. Cost and 2. the angular displacement between the rotors, I bet if you got the brackets made, you would find that the gxp rotors will make contact with the c5 caliper brackets.
