EBC Racing RP-X Front Brake Pads for Select Audi & Mercedes-Benz 2008-2021 (4.0L) - Cast Iron Rotors w/ Round Weights - DP81939RPX

Fits select 2008-2021 Audi RS7 and Mercedes-Benz AMG GT, GT S, C63 AMG, and C63 AMG S (4.0L).

EBC Racing RP-X compound is a dedicated ultra-high performance track and race pad engineered for heavy circuit use and competition vehicles. It maintains an exceptionally stable friction coefficient of 0.55 mu at temperatures exceeding 850°C, providing consistent stopping power and improved pedal feel over the RP-1 compound during the most demanding thermal cycles.

Built for durability, these pads feature stainless steel back plates to minimize heat transfer to the calipers and utilize the revolutionary Nucap NRS hook system. This mechanical retention system ensures the friction material remains securely bonded to the plate even under extreme racing conditions while remaining relatively kind to your brake rotors.
