Where is the c4 - c5 brake upgrade procedure? - ZR-1 Net Registry Forums

The factory system when in 100% proper operating condition, should be adequate enough to lock up the tires.

Under prolonged usage at a road course, you will notice fade due to lack of air circulation and and also the lack of mass. Keep in mind the ZR-1 is 3,500 lbs. Porche, Ferrari, Lambo all used Brembo 4 pistons at the time the ZR-1 was released. For some reason GM felt obligated to stay with the PBR caliper.

The C5 kit will help at the track, plus the components are cheaper to replace compared to the C4 gear.
