Compound Data Sheet

  • Race ONLY compound for specialty alloy rotors such as titanium and light weight steel.
  • Sprint cars with titanium rotors, speedway cars with plate steel rotors, and other specialized vehicles where high temperature fade and wear resistance are necessary to offset diminished cooling capacity due to rotor material and configuration.

  • Medium to high friction compound with a steadily increasing torque curve as temperatures rise.
  • Good wear and friction properties with high fade resistance for special applications where intermittent high temperature spikes are observed between periods of moderate temperature braking.
Compound Temperature Range & Torque Values
Temperature range and overall friction value are the primary considerations for pad selection. The pads must be capable of maintaining the proper amount of friction for stopping power within the temperatures that will be realized on the track during the event. Then, overall wear rate must be considered. For most asphalt and road race applications, compounds in the high temperature ranges over 1000°F range are usually necessary. Dirt track, drag race, and street performance applications usually operate at temperatures between 500° and 1000°F. Keep in mind that these are general ranges, and not absolute values. Many factors and unforeseen influences can affect brake temperatures. The best indicator for pad selection will always be on track performance. If pad fade (friction loss) due to overheating occurs, then improved cooling, a heavier rotor, or a higher temperature range pad may all become necessary.

GP200 Caliper Caliper

The GP 200 billet caliper represents the newest lightweight (only .90 pounds) caliper specifically designed for tight fit applications while utilizing a standard 2.38” lug mount. The GP 200 combines superior strength with a black anodized finish along with several new performance features. The strength of the GP 200 is a combination of process and design. GP 200 calipers are fully CNC machined from premium grade alloy billet. The FEA generated body design incorporates a highly fortified transition between the piston housings and the bridges. Strengthening this critical area of the caliper has substantially increased its resistance to deflection and body separation under load. View GP200 Caliper Calipers
