The R1 Concepts drilled black brake rotor for 2007–2017 Buick Acadia (front left) is provided as the replacement rotor for that application. The product description specifies a drilled face and black finish. Install this rotor at the front-left hub and service the paired front-right rotor at the same time to preserve balanced braking across the axle.
