Advantages Over OEM C6 Corvette Brake System

Our CP9660/355mm Radi-CAL Competition Brake Kit offers our customers the following advantages over the OEM C5 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
  • CP9660 calipers use a 18mm thick, commonly available brake pad shape
  • 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
  • No dust boots to burn up
  • Simple pad change with two bolts or quick-change spring clip, no caliper removal required
  • Lifetime professional caliper rebuilding support by Essex (at a fee)- pull off your calipers, send them to us, we clean, inspect, and rebuild them
  • Available disc burnishing service ensures that your kit arrives ready to be installed and driven hard immediately
  • Championship winning, 72 vane, fully floating, AP Racing J Hook racing discs with 12 attachment points to hat
  • Anti-knockback/anti-rattle disc attachment hardware
  • Replacement iron disc rings available at an extremely competitive replacement price
  • Disc metallurgy specifically designed to handle the temps typically seen on track offer a long service life
  • Highest quality, Spiegler stainless steel brake line with clear sheath that reduces compliance over OEM rubber design

PAD Compound:

DS1.11

The DS1.11 has a lower mu than the DS3.12 at all temperatures and can be characterized as a moderate mu pad vs. other endurance racing compounds. They require more pedal force than the DS3.12, and they have a slightly declining torque curve as temperatures rise. As they get hotter and you dive deeper into a turn, you may feel like you need to push a little harder on the brake pedal to elicit the same response (which is a feel many drivers actually prefer). Some drivers feel that the DS1.11 is more controllable on street tires than DS3.12 since ABS cannot be activated as easily. It will last a fairly long time vs. many other pad compounds on the market but does not last quite as long as the DS3.12. They are very gentle on discs at track temperatures when a proper pad transfer layer is maintained. The DS1.11 also has an outstanding max temp and fade resistance, just not quite as high as 3.12. We're not aware of anyone who has faded them, and most people differentiate between the DS1.11 and DS3.12 based on feel.

DS2500

Although we always recommend using a dedicated race pad for the track, the DS2500 is one of the best hybrid street/track pads on the market. It features the moderately high bite and solid fade resistance of a track pad, with the relatively low dust and noise levels of a street pad. When used as a street pad, it can produce some squeal on certain vehicle platforms. If you drive aggressively on the street, do some canyon runs, autocross, and maybe some light track duty on street tires, the DS2500 is tough to beat.

When used on track by 3,000+ lbs. cars with high horsepower and R Compound tires, DS2500 pad wear rates tend to be considerably higher vs. Ferodo Racing's other compounds. If you're looking for extended wear rates under those conditions, Essex would recommend the Ferodo DS1.11 or DS3.12.
