The DFC Geomet-coated rotor for 2012–2018 BMW 428i front is a hi-carbon alloy replacement that combines OE-style vane cooling with Geomet corrosion protection. Built from premium G3000/G11H18 iron castings and OE vane geometry for heat management, it’s precision mill-balanced to minimize vibration and improve stopping. A fine-turned 16 RMS finish aids pad break-in; DTV (0.10 mm) and lateral runout (0.50 mm) are controlled to maintain consistent braking performance.
