Default C5 Brake Upgrade Q??

Will a 4 wheel C5 brake upgrade (for my 84) change my wheel offset? I see that the C5 rotors are thicker then even the j55 rotors on a ZR1 or GS...I am trying to piece a Z06 set together...

I am running 17" A molds on all 4 corners now...

Thanks!

No. But you dont need the C5 rear brakes

Unless you are into some sort of competition the 12" stock brakes work fine. (a master cylinder bias spring helps)
I have heard of people moving the 13" fronts to the rear but you lose the E brake.
Check the Superior Chevrolet web site, Jeff Kopp had some info on rear C-5 conversions there.

The stock brakes on his car are not like what you have.

84-87s were smaller, and 84 had no ABS.

The 84-87 are a little smaller than the 12" brake (11.5"), but I wouldn't waste my money converting to C5 rear brakes.

Dominic,

Did you do the rears as well? What rotors did you go with? Seems like I am following everything you have done! ZF, Brakes.... LOL!

I bought C5 calipers and rotors from someone that replaced his with ZO6 brakes after only 11k miles. The rears are stock. I used Green Stuff Pads and new rotors in back. Would have liked to use Slotted Rotors. Really no need to bother with larger brakes in back. I did do a reproportioning spring from Rippie because of the bigger fronts. It stops right now.
