Default C7 brakes on a 90 ZR-1?

Gents,

I'd like to upgrade my front brakes on my 90 ZR-1.

Some initial research shows that the C7 front caliper "can" work on our cars. There's a thread on the Corvette forum where a gentleman did c7 calipers/aftermarket rotors and a spacer.

Anyone here done this already? Open to recommendations.

I currently have 19" Forgestar F14's on all (4). So, clearance won'te be an issue.

Thanks in advance!

Did you have to do any fabrication - or puchase additional parts (minus calipers/rotos) to do the swap? Thanks.

i installed a set of c6 z06 rotors/calipers/wheels and tires on my 91 zr-1. open this link and go to post #3. to mount a set of c7 calipers i would think that you would only need to find someone to manufacture a set of brackets as the bolt distance is different from the c5/c6 bolt pattern.

The fronts are easy enough w the installation of an adapter bracket on the spindle and correct brake line. Of course this assumes use of 18? wheels w the proper clearance. The rear calipers require either an adapter or use of adapter from Street Shop. The Street Shop adapter allows u to retain the eBrake. Expensive but worth it IMO.
Here?s a thread outlining the conversion. Apologies if its a dupe.
