StopTech 14-15 BMW M3 / M4 Front BBK w/ Yellow ST-60 Calipers Drilled 380x32mm Rotors

The StopTech Trophy ST60R 380 Big Brake Kit is a front, 6-piston, weight-optimized, and balanced big brake kit designed for track use in F8X M3 and M4 BMW models. Optimized for extreme track requirements, these kits feature lighter weight and specific design elements. They incorporate the Balanced Brake Upgrade® approach for optimized brake distribution, patented rotor cooling vanes for extended pad life and reduced fade, and rigid caliper designs. Trophy kits distinguish themselves with STR calipers that are 20% lighter due to extra machining, Aerorotors with 50% more airflow and a special mounting system for the rotor hat, and floating hardware between the hat and disc to eliminate pad knock-back. 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. A minimum of 19-inch wheels is required for fitment. Race calipers do not include dust boots and are for racing or track use only. For any street use, the Trophy Sport kit is recommended. These kits have been discontinued by StopTech/Centric.
