EBC Racing does however emphasize that RP X has been developed for peak on track performance, meaning higher levels of brake dust and brake noise should be expected. RP X has comparable disc wear to many other popular track/race materials; however, RP X disc wear is considerably greater than EBC Racing's other track pad RP 1 which results in high levels of brake dust. Compared to RP 1, RP X has a 25% increase in friction coefficient across its working temperature range with a much more ‘positive' initial bite. This characteristic potentially makes RP X more suitable on heavy or inherently underserved vehicles. For light medium weight vehicles, cars with non EBC Big Brake Kits fitted, or vehicles with no ABS, the less fierce nature of EBC Racing's other track material RP 1 may be preferable.
- RP-X Is Designed For Peak On-Track Performance With Higher Dust And Noise
- RP-1 May Be Better For Light-Medium Weight Cars/Non-EBC Kits Or No ABS
- Comparable Disc Wear To Other Track Materials But Higher Than RP-1
- RP-X Has A 25 Percent Higher Friction Coefficient Than RP-1
- Offers A More Positive Initial Bite Compared To RP-1
- Suitable For Heavy Or Under-Served Vehicles
