The DFC Geomet-coated drilled rotor for BMW X4 (2020–2025), right rear, is a hi-carbon alloy brake rotor finished with a Geomet corrosion coating and drilled face for thermal management. Built from premium G3000/G11H18 iron castings, it uses an OE vane configuration for heat dissipation and is precision mill-balanced. A fine-turned 16 RMS finish aids pad break-in; DTV and lateral runout meet tight tolerances.
