The R1 Concepts slotted brake rotor for 2016-2019 Cadillac ATS (left front) is a black-finish replacement meant for the front-left position. The slotted profile helps remove pad deposits and surface moisture to maintain steady pad contact during braking. Supplied as a single front-left rotor, it replaces a worn unit to help restore predictable stopping performance.
