RP-1 is a sprint race material from EBC’s motorsport division, EBC Brakes Racing. RP-1 possesses a stable friction coefficient of 0.45 from 100 - 750°C, making it suitable for heavy track use in thermally demanding applications. Below 100°C RP-1 has a usable yet slightly diminished friction level of 0.35, however, friction gently climbs to its nominal friction level of 0.45 after a couple of medium energy snubs and then stays there (i.e. it is possible to drive RP-1 from ‘cold’ however it takes a couple braking events before full brake effect is realised).
RP-1 has a progressive pedal feel with the best modulation of any material in the EBC range, allowing the driver to precisely meter out their braking inputs and trail brake with finesse.
RP-1 boasts good pad life; however, its standout characteristic is exceptionally low rotor wear. This is principally due to RP-1, unlike most other race compounds on the market, having a very low metal-fibre content. RP-1 achieves its high level of performance through adhesive friction, rather than by simply being abrasive like a scouring pad. Not only does this drastically reduce rotor wear but it also means any brake dust produced has minimal metallic content, preventing metallic ‘hot rocks’ from becoming embedded and damaging expensive alloy wheels, as is common with many other track pads. Any wheel dusting produced by RP-1 is easily washed off.
It should however be noted that, due to RP-1 being a motorsport product developed solely for track use, RP-1 is not ECE R90 homologated for road use and is therefore not legal for use on public roads in Australia.
Compared to EBC Racing’s other sprint race material RP-X, RP-1 has a 20% lower friction coefficient across its working temperature range which makes RP-1 better suited to cars where the brake system is inherently over-servoed from the factory. For cars with a ‘sharp’ brake pedal response, the less aggressive bite of RP-1 can help to promote control (for example, RP-1 works well on many Porsches, BMW M cars, performance VAG vehicles etc.). 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 will be delighted to guide you based on our considerable experience with EBC Racing’s materials.
