USR Series Sport Slotted Vented 1-Piece Front Brake Rotors (USR7125) by EBC®. Quantity: 2 Per Pack. These replacement brake rotors feature multiple slots in a narrow, more angled pattern to create a quieter running surface with a superior level of cooling. Vented center provides even temperature moderation to avoid warpage, and protective finish provides corrosion resistance on non-contact areas. The anodized layer is designed to disappear in the area that the brake pads contact the rotor. Recommended for use with EBC Greenstuff, Yellowstuff, and Redstuff pads.
