The DFC Geomet-coated rotor for 2014–2021 BMW i3 front is a hi-carbon alloy replacement rotor offering Geomet corrosion protection and OE-style cooling. Constructed from premium G3000/G11H18 iron castings with OE vane configuration, it manages heat effectively. Precision mill-balancing reduces vibration for smoother stopping and a fine-turned 16 RMS finish supports pad break-in. DTV (0.10 mm) and lateral runout (0.50 mm) tolerances are maintained for consistent performance.
