Compound Data Sheet
Use & Caution
  • Medium-high friction, good cold response
  • Gently rising torque curve, predictable engagemnet
  • Low wear rate at medium temperatures, increasing to moderate at high temperature.
  • Racing Only; Not For Street Use!
Application
  • Race ONLY compound is a value priced, proven workhorse for most weekly category asphalt late models, sprints, modifieds, and sportsman divisions.
  • Hard braking dirt late models, DIRT modifieds, and rear inboard sprint brakes with vented iron or steel rotors.
  • SCCA club racers, rally, and auto-cross.
  • High MPH drag cars if high end fade occurs with lower temperature pads.
Characteristics
  • Traditional favorite for asphalt LM's, modifieds, and sprints.
  • Modifieds, late models, and other hard braking dirt applications.
  • Intermediate weight road course, auto-cross, rally.
  • Beds easily and fully compatible with all iron and steel.
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.
