Acura RLX Brake Rotor (1) - Front Left - Stoptech - Slotted Cryo - Black - `14-`20. This StopTech slotted, cryogenically treated front-left rotor is a direct OE replacement designed for drivers who want improved performance and durability without compromising fitment.

The rotor combines StopTech's slotted face with optional cryogenic treatment and a black E-coat for corrosion resistance. Slots help evacuate gas, dust and heat for better initial bite and wet-weather response. The cryogenic process reduces residual stress in the casting, improving wear characteristics. Double-disc ground friction surfaces ensure consistent pad contact and longer service life, while symmetric vane, split-core castings promote uniform heat distribution and resistance to thermal cracking. Rotors are inspected and mill-corrected for balance to a tolerance of less than 2 oz.
