Description GIRODISC A2-282 Rear Brake Rotor Kit for BMW M2 (G87) / M3 (G80) / M4 (G82 / G83) (370x24 mm)

The GIRODISC A2-282 rear brake rotor kit is a precision-engineered 2-piece floating rotor assembly designed as a direct-fit upgrade for the BMW G87 M2, G80 M3, and G82/G83 M4 models equipped with factory iron rotors (non-carbon ceramic). Each rotor utilizes a proprietary high-carbon iron casting with superior thermal properties and features 48 curved internal vanes to maximize airflow and cooling efficiency under aggressive driving. The lightweight 6061-T6 aluminum hat is anodized for corrosion resistance and is reusable with replacement rotor rings (D2-282). In-house manufacturing of all critical components ensures tight tolerances and premium performance both on the street and the track.
