AP Racing strives to achieve the best performance out of braking systems across all types of Motorsports. The AP Racing Competition Brake Kit for the Subaru STI is the ideal set up for the driver who cannot wait to get back on the track after a long week. Made to shorten lap times, the STI Competition Brake Kit is durable, light and built with the finest materials on the market. The AP Racing Competition Brake Kit has a two piece Heavy Duty J Hook racing discs, CP8350 calipers, AP Racing pads, Spiegler Stainless Steel Brake Lines and a specific piston size meant to fit your STI perfectly and still retain the OEM master cylinder and ABS systems.
The CP8350 caliper AP Racing uses on the Competition Brake Kit for the Subaru STI is designed to be extremely lightweight, stiff, and holds a high rigidity under all track conditions, it is compact for wheel fitments and very easy to change brake pads. The finish AP Racing chose to use on their calipers is a hard anodizing layer that is appropriate for racetrack use and will give a lasting look on the STI. AP Racing's anodizing creates an abrasion resistant layer that is tougher than a paint or a powder coating and will not fall apart under extreme conditions that can lead to paint chips or debris sticking to the sides of a piston. AP Racing's CP8350 Caliper uses a machined stainless steel piston fitted with anti-knockback springs which creates a thermal barrier that ultimately keeps heat away from any brake fluids and decreasing fluid fade on track. With the stainless steel pistons and anti-knockback springs on AP Racing's CP8350 calipers, the brake pedal feel in the Subaru STI will stay crisp and responsive all day. Each CP8350 features replaceable stainless steel abutment plates, giving the pads a hard surface to slide against and move as freely as possible under braking making it easy and inexpensive to change.
AP Racing Competition Brake Kit for the STI comes with their Heavy Duty J Hook Racing Discs that were mated with high flow aluminum disc hats and were designed to handle extreme racetrack abuse, if you don't believe us just ask the professionals in NASCAR Sprint Cup and ALMS that use the same disc's. The AP Racing J Hook design gives pads a better surface to bite rather than the traditional slot design resulting in a decrease of vibrations and warping caused by cool spots. The Heavy Duty J Hook Racing Discs feature 70 vanes and a 16.5mm of air gap, maximizing air cooling and remaining a lighter weight than stock. These discs were made, tested and proven to last on the most intense track days and are easily replaceable at an affordable price range. AP Racing Competition Brake Kit for the Subaru STI is the perfect fit to push your car harder and get you around the track faster.
