StopTech racing systems and components are used in a wide variety of race series in the United States.  They are also used by various race teams in Europe and the Far East.  Design innovation, highest quality materials, and fully validated durability make these systems and components the first choice for many race teams and series. StopTech not only produces such systems, but they also race them themselves.

StopTech® Trophy Race Big Brake Kits®are bred for racing.

They include forged, lightweight StopTech® STR calipers, floating, slotted AeroRotors, stainless steel brake lines, and race engineered caliper brackets. Easily identifiable by their unique shape and finish, StopTech® Trophy Big Brake Kit® components feature a MIL-spec hard-anodizing on the Trophy STR calipers and AeroHats® that is impervious to color change or fading at extreme race temperatures.

StopTech® Trophy Kits feature ultra-high performance STR lightweight forged calipers in six-piston, four-piston or two-piston configurations. Based on the highly praised StopTech® ST-60, ST-40, and ST-22 calipers, STR calipers feature the same metallurgy and design, but are engineered to provide up to a 20-percent reduction in weight without sacrificing stiffness or performance.


StopTech® Trophy Race Big Brake Kits®

Designed specifically for motorsports competition and dedicated track cars. Unique to the Trophy Race Big Brake System is full-floating mounting hardware, which eliminates pad knock-back, and the elimination of the dust boots in the caliper. Together, these technologies optimize the brake system to provide improved performance and consistent pedal feedback under the unique combination of hard cornering and braking found on the track. Trophy Race Big Brake Kits are the ultimate in racing performance, with numerous wins and championships in World Challenge, Grand-Am, NASA and SCCA racing.

StopTech® STR Calipers

  • Stiffest aftermarket caliper available gives a consistent firm pedalstp_8x_red_wholebbk_800pwide691358AFD16E
  • Fully machined and lightweight for track action
  • Hard anodized finish that is impervious to color change or fading
  • Fully forged and extremely stiff for firmer brake pedal feel
  • Meticulously engineered 2-piece design reduces flex
  • Patented, removable center bridge further resists yaw(flex)
  • Carefully selected piston sizes for precise torque output

StopTech® AeroRotors®

StopTech® has developed several design innovations to improve rotor airflow. The patented 2-piece AeroRotors push more air thanks to curved, airfoil-shaped vanes and an air channel that widens at the trailing edge of the vanes.stp_8x_red_wholebbk_800pwide691358AFD16E

  • Specifically engineered and patented AeroVanes® for optimum cooling.
  • Patented, billet 7075 aluminum AeroHats® for improved airflow
  • Full-floating mounting hardware to eliminate pad knock-back
  • Optimized to provide even performance and consistent feedback
  • Hard-anodized hats are impervious to color change or fading


StopTech® AeroHats®

StopTech aluminum AeroHats  are lighter, and feature directional stand-offs between the rotor and mounting hat that increase airflow to the (hotter) outside face of the rotor by over 50 percent.

  • Patented design with directional stand offs between the rotor and mounting bellstp_8x_red_wholebbk_800pwide691358AFD16E
  • Increases airflow by 50%-100% over traditional 2-piece designs
  • Increased airflow reduces the temperature difference between the inside and outside rotor faces
  • Results in less distortion and better performance compared to other fully floating designs
  • Outer pad wear is reduced
