Essex Designed AP Racing Competition Brake Kit (Front CP8350/325) - 2004-2021 STI / 2002-2014 WRX

Advantages Over OEM Brake System

Our CP8350 Competition Brake Kit offers our customers the following advantages over the OEM WRX STI brake system:

• Approximately 14 lbs. of unsprung weight reduction from the nose of the car
• AP Racing calipers are the stiffest, lightest, and most technologically advanced calipers available at any price
• CP8350 calipers use a 20mm thick, commonly available brake pad shape
• Stainless steel pistons keep heat out of the brake fluid and provide an ultra-firm pedal
• Rotor hats are drilled for both 5x100 and 5x114.3
• 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, 70 vane, fully floating, AP Racing J Hook racing discs with 10 attachment points to hat
