The R1 Concepts slotted brake rotor for 2015-2019 Cadillac CTS (left front) is a black-finish replacement meant for the front-left position. Its slotted surface helps clear pad deposits and reduce surface moisture to maintain steady contact between pad and rotor. Supplied as a single front-left rotor, it replaces a worn part to help restore reliable braking feel at that wheel.
