Compound Data Sheet

  • Application specific compounds are elements of Wilwood ProMatrix pad and rotor upgrade kits.
  • Where available, ProMatrix compounds are designated for use in the OE calipers on OE or performance upgraded rotors.

  • True dual-sport Pro-Matrix performance street and track compound.
  • Quiet running with lowered dust than OE compounds.
  • Unique composite formula provides clean, quiet, and long running on the street, with high friction and high temperature fade resistant to withstand extreme braking cycles during auto-cross and track day advents.
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.
