ER-1 has been developed by Hawk Performance for the endurance racing market with a simple goal; offer a higher coefficient of friction than competing endurance pads while maintaining matched or improved lifespan. Years of testing across America's most prestigious races has resulted in a well-rounded compound that offers ideal modulation and pedal communication, with ground breaking friction stability across a thermal range as high as 1,600°F. This consistency of performance, hour after hour, makes it ideal for not only endurance racing, but HPDE, track days, time trials and even sprint racing. Superior Pad & Rotor wear. .490 Inch. Consistent medium-to-high friction. Specific emphasis on modulation, release and pedal communication. Ideal for light-to-medium weight vehicles in HPDE, Track Day events, Time Trials, or Endurance Racing. Higher coefficient of friction than competing endurance pads, wtih matched or improved lifespan. All Hawk Performance compounds are not compatible with carbon ceramic rotors. Hawk pads are designed to work with Iron/Metal rotors. Medium to High torque. 400-1600 F operating temperatures. 700-1100 F optimal temperatures. Set of 4.
