StopTech has introduced a new competition brake system designed for cars built for road racing and high performance street use. The new 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.

SRT-60

• ALL finished parts are 100% leak down and pressure tested to 2500 PSI
• Uses a popular pad shape readily available in over 15 street performance and race friction compounds
• Over 19 different piston size combinations available to tune brake torque to the needs of each individual application
• Differential piston sizes minimize pad taper for longer pad life and a firmer pedal

• ALL finished parts are 100% leak down and pressure tested to 2500 PSI
• ST-40 uses standard FMSI D372 pad
• Any combination of 8 piston sizes available to match kit to vehicle application
• Differential piston sizes minimize pad taper
• Dust boots are standard on Sport Trophy kits
• Same caliper used by top Speed® World Challenge and Grand-Am Cup Teams

STR-22
