BRAKE UPGRADE INCLUDES:
STILLEN is excited to announce the AP Racing World Radi-CAL II by STILLEN big brake kit for BMW 330i (E90), 330i (E92), 330i (E93), 335i (E90) and 335is (E92). This big brake kit consists of 4 piston rear calipers, 360x28mm (14.2”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.
Options & Styles
Matching the vehicles weight and thermal capacity required at maximum speed, all while maintaining proper brake balance and peak performance for the 3 Series BMW E46, E90, or F30 chassis.This big brake kit will perform as well on the track as it does with everyday road use, and is great for the spirited daily driver right alongside the track enthusiast. Utilizing larger and wider AP Racing rotors for greater thermal capacity and the new AP Racing Forged Radi-CAL 6-piston calipers for the front and 4-piston calipers in the rear, STILLEN Engineers developed mounting hats and brackets to specifically fit the BMW 3 Series 325i, 328i, or 335i. These components are designed and engineered in STILLEN's R&D department, and manufactured at STILLEN's in-house machine shop using the latest technology in CNC Lathe and Mill machining. Proper rotor sizing, caliper configuration and pad selection were chosen specifically for the E46, E90, and F30 to deliver maximum brake performance.
AP Racing is the best of the best when it comes to brake technology in motorsports.. where their Radi-CAL racing calipers have dominated Formula 1, NASCAR Sprint Cup, ALMS, World Rally Championship (WRC) and many other racing series with countless wins, which are the direct result of AP Racing's superior braking technology. The new AP Racing Radi-CAL High Performance Road Calipers are pressure FORGED versus the major competitors cast calipers. These pressure FORGED calipers are 25% lighter and 20% stronger than cast calipers of the same size in the same performance category. The entire Radi-CAL high performance road system is born from the Radi-CAL systems designed by AP Racing for Formula 1 and NASCAR.
