Will C5 brake rotors fit - ZR-1 Net Registry Forums

Hi to all

trawled threads for a perfect answer to this Q and cant find so here goes

Ive noticed my rotors have become quite pitted and I have a line on a set of clean C5 rotors from a 2001 manual coupe in the UK ..but without callipers......

Q1...can the rotors directly replace front and rear 92 zed stock items, and can l continue to use the stock callipers......

Or is there other work to do ?

Dave, I do believe that swap will not work. C4 rotors are a smaller diameter?

I confess that I'm not 100% sure on this, but I know to do a C5 front conversion to a C4 you need different caliper mounting brackets. A C5 caliper is larger than a C4 ZR-1 caliper, and I do believe a C5 rotor is larger in both diameter and thickness than a ZR-1 C4 rotor.

Thanks for that tom......l was guessing it wasnt going to be a straight swap....may just as well get what fits first time....something that utilizes the stock hub/caliper but with added stopping

It's really unlikely it would clear the caliper mounting bracket. That thing sits pretty close to the stock rotor on both sides, and the C5 rotors are .15" thicker.
