The DFC Geomet-coated rotor for 2016–2025 BMW M440iX rear is a hi-carbon alloy direct-fit rotor that adds corrosion-resistant Geomet coating to OE-style vane cooling. Made from premium G3000/G11H18 iron castings with OE vane geometry, it offers effective heat dissipation. Precision mill-balancing minimizes vibration for smoother stopping; a fine-turned 16 RMS finish aids pad break-in and DTV (0.10 mm) plus lateral runout (0.50 mm) limits are controlled.
