Overview

Show original supplier description
The Zimmermann Coated Brake Rotor provides a factory-style replacement for the rear braking system, utilizing high-carbon steel for better heat management during operation. The disc is fully finished with an anti-corrosion zinc dichromate coating that covers the rotor hat, friction surface, and internal cooling vanes, ensuring the component maintains its appearance and effectiveness over time. These rotors are specifically designed for several F3X and F33 chassis BMW models, including the 320iX, 328iX, and 428iX. It is important to note that this part is not compatible with vehicles equipped with the factory M Sport package or M Sport brakes upgrade (S2NHA). For F33 428i/428iX convertible models, fitment is limited to vehicles equipped with the N26 SULEV low-emissions engine; ensure your vehicle's emissions sticker is labeled SULEV before installation. Correct bed-in procedures must be followed after installation to ensure optimal performance. This product is sold as a pair of rotors.
