Endurance racing pad, similar levels of power to RC6 but around 30-40% more life. This is only of use to you if changing the pads will cost you time in pit stop changes. They're also extremely easy on rotors. They initially appear expensive, but when you factor in how long they will last (along with your rotors), they're actually a tremendous value. While having slightly lower bite than the RC6, the RC6E still has more bite than most other race pads on the market.
