EBC Racing does however emphasise 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 Racings other track pad RP-1 which results in high levels of brake dust. Compared to RP-1, RP-X has a 25 percent 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 under-servoed 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 Racings other track material RP-1 may be preferable.

• RP-1 May Be Better For Light-Medium Weight Cars; Non-EBC Kits Or No ABS
• RP-X Is Designed For Peak On-Track Performance w/Higher Dust And Noise
• 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-Servoed Vehicles
