Description
Advantages Over OEM Brake System
Our CP9450/365mm Radi-CAL Competition Brake Kit offers our customers the following advantages over the OEM brake system:

Approximately 22 lbs. of unsprung weight reduction from the rear of 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 means 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
