The DFC GeoSPEC coated drilled rotor for the left rear of 2020–2025 BMW X4 is a direct-fit replacement that improves corrosion resistance and pad bedding. Ready to install with no pre-degreasing required, it is precision cut and mill-balanced to reduce vibration and ensure smooth stops. Constructed from premium G3000/G11H18 iron and finished superior to zinc, the non-directional face supports faster break-in and extended reliable performance.
