StopTech's latest racetrack and competition brake system comes with the new Trophy STR lightweight forged calipers in six-piston, four-piston and two-piston configurations. Based on the StopTech ST-60, ST-40, and ST-22 calipers, STR calipers feature the same metallurgy and design, but are engineered to provide a 20-percent reduction in weight without sacrificing stiffness or performance. STR calipers are also available in Sport Trophy kits designed for production street driven vehicles which utilize dust boots, anti-rattle rotor mounting hardware and include StopTech Street Performance brake pads. All existing StopTech kits can be ordered as Trophy or Sport Trophy kits.
