Direct replacement REAR brake rotor for F30 320i/328i and F32 428i (RWD models) and F33 428i/428iX convertibles (with N20 engine, not N26 SULEV).
Zimmerman rotors are finished with an anti-corrosion zinc dichromate coating over the entire rotor. This coating is applied over the rotor hat, face, and through the vanes for total corrosion protection. Even after a year of use the Zimmerman coating doesn't change color or effectiveness. The rotors are ready to use after correct bed-in procedures have been done. In addition, Zimmerman uses a high carbon content in their discs for improved thermal performance.
