Hawk Brake Pad ER-1 HB803D.639

Developed by Hawk Performance specifically for endurance racing, ER-1 brake pads deliver a higher coefficient of friction than competing compounds while maintaining equal or improved lifespan. After years of rigorous testing at top-tier U.S. racing events, ER-1 offers exceptional modulation, pedal communication, and groundbreaking thermal stability up to 870°C (1600°F). Consistent performance lap after lap makes it a top choice for endurance racing, HPDE, track days, time trials, and even sprint racing.
