EBC USR Blackdash slotted front rotors for 2017+ Audi A4 (B9) feature a narrow‑slot design to cut wind noise while helping brakes run cooler. The Black Thermic coating provides corrosion protection and a finished appearance. These slotted rotors maintain flat, parallel pad contact and are intended as a quieter sport rotor option when used with compatible high‑friction pads.
