  • Brake pads are NOT included with our system. Racing brake pads are a highly personal choice. Many manufacturers include a set of inexpensive, low quality pads with their brake kits. Rather than artificially inflating the price of our system with a set of pads you probably don't want anyway, we've decided to remove the cost from our system and allow our customers to choose the pads that best suit their needs/wants. When purchasing our kit, you are able to choose one set of front pads at a substantial discount vs. the retail price. Please use the drop-down menu to select your pads.

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 10 lbs. of unsprung weight reduction vs. the OEM standard front iron brake package
  • 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
