EBC Racing Front RP-X Track & Race Brake Pads Subaru impreza WRX 2.5 Turbo 2007-2012- EBC-DP81661RPX

EBC Racings' RP-X compound is an ultra-high performance track and race pad designed for performance vehicles driven hard on track and for dedicated race cars. RP-X has a very stable friction coefficient of 0.55?? up to and beyond 850??C, making it an excellent performer for even the most demanding vehicle applications.RP-X also has a high friction level from cold, requiring no warmup to achieve maximum braking effect which makes this material well suited for sprint race and hill climb events. Although RP-X is not R90 homologated for use on the public roads in EU member states, the fact this material possesses excellent cold performance means RP-X can be safely used for driving to/from motorsport events (where local laws permit).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 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 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 Racing's other track material RP-1 may be preferable.
