Advantages Over OEM Brake System
Our CP9449/365mm Radi-CAL Competition Brake Kit offers our customers the following advantages over the OEM brake system:
- Approximately 10 lbs. of unsprung weight reduction from the car
- AP Racing Radi-CAL calipers are the stiffest, lightest, and most technologically advanced calipers available at any price
- Calipers use a 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 one bolt, 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
- Anti-knockback/anti-rattle disc attachment hardware
- Replacement iron disc rings available at an extremely competitive replacement price ($375 each).
- 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
