Grand Sport brake calipers
96 Grand Sport calipers:
We‘re all pretty familiar with the differences on the front calipers, is there any real difference in the rears other than being powder coated black? Any ideas on the going $ these days, front and rear? |

Re: Grand Sport brake calipers
Fronts had “CORVETTE” in the casting. C5s followed this

Re: Grand Sport brake calipers
Fronts also had extra cooling fins, that may or may not have added a little extra strength.

Re: Grand Sport brake calipers
They are thicker and stiffer in the area at the center of the "C". As a result they flex less than ZR-1 calipers. This gives them a sharper edge to the bite when applied hard and sharply.

Re: Grand Sport brake calipers
There’s a full rebuilt set on eBay right now. Not cheap but correct.
