Compound Data Sheet
    Use & Caution:

  • Ultimate high friction pad with aggressive initial response
  • Immediate low tempeature response.
  • Low wear rate
  • Racing Only; Not For Street Use!
    Application:

  • Race ONLY compound used in ARCA, ASA, ALMS, Grand-AM, NASCAR, REMAX, SCCA, USAC, and other severe duty oval, road course, and off-road series that require an aggressive response and durability in the highest temperature ranges.
  • Lightweight sprints and club sport racers using steel plate rotors that require fast response at low temperatures with resistance to fade during periodic or temporary high temperature spikes.
    Characteristics:

  • Immediate cold response with highest friction values at all temperatures.
  • Severe duty use on oval tracks, road courses, and other applications that require immediate high torque response.
  • Long wear rate for sustained high heat braking.
  • Compatible with all iron and steel rotors.

PolyMatrix A 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.
