Compound Data Sheet
    Application:

  • High performance street / strip, drag race, and track day categories using vented iron rotors.
  • Light to medium braking on dirt tracks including late models, modifieds, sportsman, and street stocks.
  • Disc brake conversions on street rods and muscle cars.
    Characteristics:

  • Compatible with all types of aluminum, steel or iron rotors.
  • Most aggressive friction with aluminum rotors on sprint cars.
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.
