Whats in the box?

  • One pair AP Racing CP9660 Radi-CAL Pro5000R racing calipers

Advantages Over OEM C6 Brake System

  • Approximately 8 lbs. of unsprung weight reduction from EACH front corner vs. base C6, or 16 lbs. of unsprung weight reduction from the car. Offers 19 lbs. unsprung weight reduction from front of C6 Z06.
  • AP Racing Radi-CAL calipers are the stiffest, lightest, and most technologically advanced calipers available at any price

  • Ventilated, domed back, stainless steel pistons keep heat out of the brake fluid and provide an ultra-firm pedal
  • Mitigation of pad knockback via anti-knockback springs behind the caliper pistons
  • Anodized caliper finish that is resistant to wear and deterioration at elevated temperatures
  • Stainless steel caliper hardware for a long caliper service life under frequent pad change conditions
  • High temperature, low drag seals that will hold up to track temps= less rebuilding and longer service life
