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.
