HAWK Performance ER-1 Motorsports Brake Pads Rear - HB803D.639

Hawk ER-1 Endurance Compound

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
• 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
