Compound Data Sheet
Application:

  • Race ONLY compound used in 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:

  • Improved friction formula for heavy braking asphalt ovals, extreme braking on dirt, and all types of off-road and road course applications.
  • Predictable and linear response with excellent modulation on iron and titanium rotors.
  • Long wear rates with iron and steel rotors.
  • High torque on Titanium rotors.
  • Very high heat fade resistance.
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.
