The DFC Geomet-coated rotor for 2010–2019 BMW Alpina B7L xDrive left front is a hi-carbon alloy replacement rotor that resists corrosion while preserving OE cooling performance. Using premium G3000/G11H18 iron castings and OE vane configuration for heat management, it’s precision mill-balanced for smooth stopping and low vibration. The fine-turned 16 RMS finish helps pad break-in and Geomet protection plus DTV (0.10 mm) and lateral runout (0.50 mm) limits support reliability.
