BIG BRAKE KIT 2 PIECE ROTOR, FRONT

The StopTech Trophy ST60R 380 Big Brake Kit is a front, 6-piston, weight-optimized, balanced big brake kit specifically designed for the E46 M3. It is optimized for exclusive track use, featuring lighter ST60R forged calipers (20% lighter) and Aerorotors with 50% better cooling airflow. The calipers and rotor hats have a hard-anodized coating. The kit includes forged caliper brackets with mounting studs, brake pads, and stainless steel brake lines. It utilizes StopTech's Balanced Brake Upgrade(R) approach, patented rotor cooling vanes, and a stiff caliper design. Pad knock-back is eliminated by using floating hardware between the hat and disc. The kit is available in "Race" (with SR33 Race pads, no dust boots on caliper pistons) and "Sport" (with 309 Sport pads, with dust boots) specifications.
