Everything about the StopTech Trophy kits have been optimized for exclusive track use. This means lighter weight and specific design features dictated by extreme track requirements. BMW Trophy Kits feature all of the great advantages of a regular StopTech Big Brake Kit: the Balanced Brake Upgrade(R) approach that optimizes brake distribution to improve traction at all four corners, patented rotor cooling vanes for longer pad life and less fade, and the stiffest caliper designs in the industry.
Where Trophy kits become extra special is in the details: the STR calipers are 20% lighter thanks to extra machining, the rotors have 50% more air airflow with a special mounting system for the rotor hat, and pad knock-back is eliminated by using floating hardware between the hat and disc. All of these features would go unnoticed on a regular street BBK but are advantageous for a track or race application.
StopTech Trophy BBK are built with a singular purpose: uncompromised braking performance on the racetrack. With a ultra-rigid caliper design, less brake fade, model-specific piston sizing, and abundant pad options StopTech Trophy brakes will boost your driving confidence and lower your lap times! Drivers in World Challenge, Grand-Am/IMSA, NASA, and SCCA have already benefited from the Trophy brake advantages with numerous wins and championships.
Race calipers do not use dust boots on the caliper pistons and are only sold for racing or exclusive track activity only. Caliper dust boots play a key role in preventing debris from damaging the inner piston seals and causing a very dangerous loss in brake pressure. For any street use, please select the Trophy Sport kit. As with any racing braking system, periodic rebuilds and regular fluid changes using an appropriate fluid are strongly advised.
Trophy calipers are only available in dark-grey military-spec hardcoat.
