Compound Data Sheet
Application:

  • Most dirt track applications including super late models, modifieds, and rear inboard sprints using vented iron rotors.
  • Light to medium duty road racing and track day events.
  • Drag racing with iron or steel rotors.
  • Performance street category competition.
Characteristics:

  • Consistent, linear response through temperature range.
  • Baseline for light to intermediate dirt applications with vented iron rotors.
  • Drag racing with steel rotors.
  • Auto-cross and lighter duty road racing.
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.
