The ultimate street braking system, with naturally anodized lightweight components adapted from our racing program. They use the same STR calipers, AeroRotors® and AeroHats® as the Trophy Race BBKs, but add silicone dust boots to extend service intervals and anti-rattle rotor mounting hardware for quieter street operation. They also include StopTech® Street Performance brake pads for high performance street and occasional track use, and StopTech Stainless Steel Lines. Any StopTech BBK can be ordered as a Trophy Sport Kit by specifying it on the order form.
