The DFC Geomet-coated drilled left-front rotor for 2007–2013 Porsche 911 is a hi‑carbon alloy replacement intended to preserve braking consistency and manage heat. It features premium G3000/G11H18 iron castings, OE vane geometry for cooling, and is precision mill-balanced to reduce vibration. The fine-turned 16 RMS finish improves pad break-in while Geomet coating offers corrosion resistance; DTV 0.10 mm and lateral runout 0.50 mm are controlled.
