StopTech’s legacy two-piston caliper is popular for rear axle applications that use varying thicknesses of vented rotors. Like the STR-60 and STR-40, the STR-22 is the benchmark for two-piston calipers in design content and versatility. It utilizes StopTech’s range of available piston sizes, while controlling pad taper with an offset bore and steel abutments.

  • MIL-spec hard anodizing on calipers resists color change or fading
  • Forged and weight-optimized, up to 20 percent lighter than standard calipers
  • Stiffest calipers available with patented strengthening bridge for improved pedal feel and modulation
  • Eliminates pad taper wear and provides consistent, confidence-inspiring performance
  • Calipers and piston sizing specifically matched to each application
