• Features AP Racing CP9660 Radi-CAL calipers
• 372x34mm, 84 vane AP Racing disc
• Saves roughly 6 unsprung lbs. from nose vs. OEM brakes despite considerable size increase
• Every component designed to resist the heat of extended track sessions
• Pistons sized properly to allow for seamless integration with OEM master cylinder and ABS system
• Designed to work with OEM rear brakes or the Essex/AP Racing rear BBK

“Radi-CAL” is a blanket term used to describe AP Racing’s patented asymmetrical brake caliper design. Radi-Cal technology is grounded in Computer Aided Design (CAD) and Finite Element Analysis (FEA), and allows for organic, alien-looking designs that are a radical departure from conventional caliper designs of the past. Radi-CAL's are widely considered the pinnacle of current brake caliper technology. Since their inception in 2007, these revolutionary calipers have amassed a lengthy string of race victories at all levels of professional motorsport, while redefining brake performance expectations. 

The key benefits of the Radi-CAL design:

• Massive Stiffness Increase- A 30+ % increase in both static and dynamic stiffness vs. conventional calipers allows for far less deflection under load, which means superior pedal feel & modulation, more even pad wear, and longer caliper service life.
• Considerable Mass Reduction- Removing all extraneous caliper mass lowers the caliper weight, despite the huge stiffness increases.
• Optimized Airflow- Air moves around and through the caliper more efficiently, providing superior heat evacuation and cooling.
• Efficient Packaging- The asymmetric caliper profile and internal fluid porting allows the caliper to fit into tighter spaces.

Advantages Over OEM Brake System

Our CP9660/372mm Radi-CAL Competition Brake Kit offers our customers the following advantages over the OEM brake system:

• Approximately 6 lbs. of unsprung weight reduction despite a considerable size increase over stock
• 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, 84 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
