Wheel Compatibility with GS Brakes - ZR-1 Net Registry Forums

Hib Halverson · 09-13-2022

I had '96 GS fronts on "Barney,: the C4 ZR1 I once, owned, for probably 2/3rds of the 20 years I had it.

The GS fronts are modestly stiffer across the "bridge" than were the standard J55 fronts. That makes for less caliper spreading, more force applied to the brake disc and a marginally harder pedal during aggressive braking.

The GS rears are the same as all J55 rear calipers except they were black powder coated.

Any wheel that works with a standard J55 front will work with GS fronts.
