STILLEN is excited to announce the AP Racing World Radi-CAL II by STILLEN big brake kit for Infiniti FX35, FX37 and FX50.  This big brake kit consists of 4 piston rear calipers, 380x28mm (15”x1.1”) 2 piece floating rotors, high performance brake pads, billet aluminum mounting brackets and braided stainless steel brake lines.

During their dynamic testing they noticed that the caliper was actually twisting diagonally due to the forces created by the RPM and mass of the rotor interacting with the friction created by the application of the brake pads. The solution was to reinforce and stiffen the caliper in key locations to counteract this force.

Choosing the best big brake kit for your S51 Infiniti just became extremely easy, with the introduction of the next generation of braking performance; The AP Racing Radi-CAL II 4 Piston Brake System by STILLEN. This show-quality setup will catch anyone's eye, and has the performance to back it up. Now you can benefit from this brake technology on your FX35, FX37, FX50, S51 and have the braking confidence formerly available only to top motorsport teams.

The AP Racing designed Radi-CAL II 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. Taking this born-from-motorsports technology, STILLEN Engineers utilize AP Racing Rotors and the new AP Racing Forged Radi-CAL 6-piston calipers for the front and 4-piston calipers in the rear to develop these new brake kits designed specifically for your Infiniti FX35, FX37, or FX50. 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 S51 to produce maximum braking performance, with a striking look no enthusiast could miss.

The entire Radi-CAL II system was created from the Radi-CAL system designed by AP Racing for Formula 1 and NASCAR. 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.
