Pad Compound Selection Guide  

Wilwood Pad Compounds:
Wilwood brake pad compounds are the results of three decades of experience and continual development to provide optimized braking and driver feel for all types of motor sport and competition applications. This selection guide is intended to provide general characteristics and applications for each compound. On-track testing and driver evaluation however, will always remain the determining factor to final pad selection.

Pad Selection Tips:

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.
