The DFC Geomet-coated hi-carbon alloy rear rotor for 2003–2008 BMW Z4 supplies OE-level stopping performance and corrosion resistance in a direct replacement rotor. Built with G3000/G11H18 iron castings and OE vane configuration to enhance heat dissipation, it’s precision mill-balanced for smoother braking and fine-turned to 16 RMS for improved pad break-in. Geomet coating helps protect the finish; DTV ≤0.010 mm, lateral runout ≤0.050 mm.
