The R1 Concepts drilled-and-slotted black rear-left brake rotor for 2013–2019 Cadillac ATS is a vehicle-specific rotor made to match the listed years and wheel side. The drilled-and-slotted face with a black finish renews the rear axle's braking surface and provides a coordinated look while conforming to the original mounting and orientation.
