The Hawk Performance ER-1 Brake Pads for BMW are engineered for drivers who demand race-proven braking performance on track days, HPDE events, time trials, and sprint racing. Developed through years of extensive testing in some of the world’s most prestigious racing environments, the ER-1 compound was created with one goal in mind: deliver a higher coefficient of friction than competing track pads while maintaining or improving pad longevity.

The ER-1 offers exceptional pedal feel, modulation, and communication, giving drivers consistent and predictable braking feedback lap after lap. With friction stability across a thermal range up to 460°C, these pads resist fade and maintain stable, repeatable performance even in extreme track conditions.

This balance of high friction levels, consistent bite, and durability makes the Hawk Performance ER-1 ideal for those who push their BMW to its limits on the track but also want a pad that lasts. If you’re participating in HPDE, track days, time trials, or sprint racing, the Hawk Performance ER-1 Brake Pads offer the control, confidence, and endurance needed to perform at your best from the first lap to the last.

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.

  • Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content.  Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
  • Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
  • Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
  • Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
