Choosing the best brake kit for your Subaru Impreza WRX just became extremely easy, with the introduction of the next generation of braking performance; The AP Racing Radi-CAL Brake System by STILLEN.
This show-quality setup will catch anyone’s eye, and has the performance to back it up. AP Racing has been dominating the highest level of motorsports for over 50 years, such as Formula 1, NASCAR Sprint Cup, ALMS, World Rally Championship (WRC) and many others.. and most importantly winning. Now you can benefit from this brake technology on your Subaru Impreza WRX, and have the braking confidence formerly available only to top motorsport teams.
The AP Racing designed Radi-CAL calipers are FORGED versus the major competitor's cast calipers. These FORGED calipers are 25% lighter and 20% stronger than cast calipers of the same size in the same performance category. The entire Radi-CAL system was created from the Radi-CAL system designed by AP Racing for Formula 1 and NASCAR.
Taking this born-from-motorsports technology, STILLEN Engineers utilize AP Racing Rotors and the new AP Racing Forged Radi-CAL 4-piston calipers for the front specifically for the 2015 Subaru Impreza WRX. All of the mounting hats and brackets are designed and made in-house at STILLEN's machine shop, using the latest technology in CNC Lathe and Mill machining. Caliper configuration, pad selection and proper rotor sizing are all chosen for the Subaru Impreza WRX to produce maximum braking performance, with a striking look no enthusiast could miss.
Not all brake systems are created equal. In fact, most big brake kits aren't really suited towards heavy track use either. While they usually increase thermal capacity and may solve small fading issues, they generally aren't optimized for hardcore track use. Essex set out to design a couple of brake packages that can take anything thrown at them...and then some.
