Hawk ER-1 Brake Pads- FRONT - 18-21 STI, 2024+ WRX TR/RS w/ Brembos

ER-1

ER-1 has been developed by Hawk Performance for the endurance racing market with a simple goal; to 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 have resulted in a well-rounded compound that offers ideal modulation and pedal communication, with groundbreaking 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.
