This brake disc is designed for vehicles with M Performance or M Sport brake systems and features precision-engineered perforations that quickly dissipate moisture and brake dust from the rotor surface, improving brake response and wet weather braking performance. The floating two-piece construction with steel pin connections allows the friction ring to freely expand under thermal stress, reducing heat-related distortion.
