Application: Race ONLY compound for specialty alloy rotors such as titanium and light weight steel. Sprint cars with titanium rotors, speedway cars with plate steel rotors, and other specialized vehicles where high temperature fade and wear resistance are necessary to offset diminished cooling capacity due to rotor material and configuration. Characteristics: Medium to high friction compound with a steadily increasing torque curve as temperatures rise. Good wear and friction properties with high fade resistance for special applications where intermittent high temperature spikes are observed between periods of moderate temperature braking. 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.Pit Stop USA offers Wilwood Composite Metallic Brake Pads - Fits Billet DynaPro Narrow Mount, Billet NDL 150-10290K at low everyday prices.
