EBC Brakes RP-1 rear brake pads E9X M3

Designed for vehicles driven hard on track, RP-1™ possesses a moderately high friction level of 0.45 between 100 – 750°C (200 – 1400°F). The more progressive response characteristic of RP-1™ makes it well suited for inherently ‘over-servoed’ vehicles where a softer pad material is desirable to allow greater finesse when on the brakes. RP-1™ also works superbly when used with many competitors (non-EBC) Big Brake Kits, where the more progressive pad response helps to negate the over-servoed sensation often experienced after fitment of larger diameter brake discs and calipers with large piston displacements. EBC Racing would like to emphasise that it is not a case of RP-1™ being ‘less good’ than RP-X™, rather it is ‘different’ and designed to provide a distinctly different response characteristic (less aggressive bite) which some drivers may prefer.
