Stoptechs 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 in most applications.
