R1 Front Left Black Drilled Brake Rotor 2007-2021 BMW 228I/228I Xdrive & More - 623-31089L

R1 Front Left Black Drilled Brake Rotor 623-31089L is engineered for select 2007-2021 BMW 228I, 228I Xdrive and additional listed models applications. This eLINE Black Series rotor combines a performance-focused cross-drilled braking surface with a black zinc finish designed to help protect exposed non-friction areas from corrosion while delivering a clean, aggressive appearance. Precision-drilled and countersunk openings are designed to promote heat dissipation during repeated braking, making this rotor a strong street-performance replacement for drivers who want both function and style. This is a side-specific Front Left rotor; verify the axle and side before ordering.

R1 eLINE Black Drilled Brake Rotor Series:

R1 eLINE Black Series Drilled Brake Rotors combine performance-oriented cross-drilled construction with a protective black zinc finish for drivers looking to upgrade braking appearance, heat management and corrosion resistance. Precision-drilled openings help promote heat dissipation during repeated braking, while countersunk hole edges are engineered to reduce stress concentration around the drilled surfaces. Built around application-specific replacement dimensions, the eLINE Black Drilled series offers a performance-focused rotor option for street-driven cars, trucks and SUVs.

The rotor arrives with a full black zinc finish. During proper bedding, the coating on the brake-pad contact surface naturally wears away to expose the metallic friction surface while the black finish remains on protected non-contact areas such as the rotor hat. Rotor construction, dimensions and fitment vary by application, so axle position and left/right orientation should always be matched to the individual manufacturer part number.
