The R1 Concepts drilled black brake rotor for 2003–2009 Mercedes‑Benz E320 (front left) is a replacement rotor with a drilled face and black finish sized for the left front position. The description calls out years and side to aid fitment confirmation. Replacing the matching front rotor alongside this unit helps maintain even braking characteristics across the axle.
