The DFC GeoSPEC coated plain rotor for 2006–2021 BMW 323i rear applications supplies an OEM-form replacement with enhanced corrosion protection. Precision cut and mill-balanced to minimize vibration and improve stopping consistency, it’s constructed from G3000/G11H18 iron castings for strength. The non-directional finish helps break-in quickly, and the rotor ships ready to install without extra pre-degreasing.
