ER-1 has been developed by Hawk Performance with a simple goal: Offer a higher coefficient of friction than competing 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 1600F. This consistency of performance, hour after hour, makes it ideal for HPDE, track days, time trials, even sprint racing and more.
This is a REAR pad set and is specific to the 2008-2013 BMW 135i Brembo single piston rear caliper. This caliper was also used on some E9X 3 Series models with the optional M Performance Big Brake Package (which is not a common fitment, but is sometimes retrofitted on 2006-2013 3 Series models).
• 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, or Time Trials
• Higher coefficient of friction than competing pads, with matched or improved lifespan
• Medium to High torque
• 400-1600 F operating temperatures
• 700-1100 F optimal temperatures
All Hawk Performance compounds are not compatible with carbon ceramic rotors. Hawk pads are designed to work with traditional Iron/Metal rotors.
This is a racing brake pad application, and as such is not recommended or designed for street use.
