Product Description

RP-X is a high-torque material designed for sprint race and trackday use. RP-X possesses a friction coefficient of 0.55 and is stable from 0 – 750°C making it an excellent compound for thermally demanding motorsport applications. The fact RP-X achieves full brake effect from cold means RP-X is a popular choice for Time Attack, Rallycross and Hillclimb events, where no warm-up is possible, meaning drivers require 100% brake effect from the first pedal application.

RP-X is developed solely for use in motorsport and is not ECE R90 approved, making it illegal to use RP-X on public roads in Australia. Furthermore, although RP-X meets the standard for obtaining the highest ‘N’ for its environmental credentials, as it contains zero copper, zero asbestos and zero heavy metals, given RP-X’s motorsport focus this material has not been formally tested according to this US environmental regulation.

RP-X gives 20-30% longer pad life than RP-1, especially when run at higher temperatures, however, the high-torque nature of RP-X means it is much more aggressive on brake rotors (but no worse on rotors than many other race materials on the market). RP-X tends to work best on vehicles that have inherently under-servoed brakes, where RP-X’s more aggressive bite helps to supplement braking power without being overwhelming (in this regard, RP-X works well on Japanese and Korean manufactured vehicles, which typically have lower brake assistance than performance cars originating from Europe and elsewhere).

If you’re unsure whether RP-1 or RP-X is likely to be better suited to your vehicle or driving style, please speak to a member of our technical team who’ll be delighted to guide you based on our considerable experience using both materials.
