Brake Pads Wilwood 150-22-10120K BP-22 Street Performance Racing Pads .755 - USA-WIL-150-22-10120K - Street Performance / Racing Pads BP-22 Compound  Pad Characteristics Ceramic-based medium friction pad Reduced dust and noise Holds steady friction through most of the temperature range Reduces rotor wear without giving up torque Repeatable smooth engagement and response modulation builds confidence Pad Applications Street performance Autocross Street & Strip Consumer-grade Towing Rotor Material Iron Steel Stainless Steel Pad Dimensions Thickness(in) .755 Area(in²) 12.69 Volume(in³) 6.81 Bedded N Dust & Noise Ratings Dust Production Rating Very Low Pad Noise Rating Very Low Temperature range and overall friction value are the primary considerations for pad selection. The pads must maintain the proper amount of friction for stopping power within the temperatures that will be realized on the track. Overall wear rate must also be considered. For most asphalt and road race applications, compounds in the high-temperature range over 1000°F 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, improved cooling, a heavier rotor, or a higher temperature range pad may become necessary.
