The DFC Geomet-coated rear rotor for 2016–2020 BMW 740i xDrive is a hi-carbon alloy replacement designed to restore braking confidence and resist corrosion. Made from premium G3000/G11H18 iron castings with OE-style vane configuration for efficient heat dissipation, it is precision mill-balanced and fine-turned (16 RMS) to reduce vibration and support pad break-in. Geomet coating offers corrosion protection; DTV ≤0.10 mm and lateral runout ≤0.50 mm keep braking predictable.
