The EBC USR Slotted Rotor Kit pairs S4 Redstuff pads with large diameter vented USR rotors and includes caliper lube to provide a complete front brake upgrade. Pads use aramid fiber with ceramic granules, full shims and EBC Brake‑in coating to reduce dust and speed bedding. Vented rotors carry Geomet black anti‑rust protection and the kit fits as a direct replacement without modification to stock hardware.
