The DFC Geomet-coated rotor for 2013–2020 BMW 440i xDrive Gran Coupe front is a hi-carbon alloy direct-fit rotor that resists corrosion and preserves OE cooling performance. Built from premium G3000/G11H18 iron castings with OE vane geometry, it provides solid heat dissipation. Precision mill-balancing reduces vibration for smoother stopping, and a fine-turned 16 RMS finish aids pad break-in. Geomet protection plus DTV (0.10 mm) and lateral runout (0.50 mm) control ensure reliable braking.
