The DFC slotted Geomet-coated rotor for 1982–1985 Porsche 928 (right front) is a direct-fit performance replacement that improves pad bite and heat management. Made from hi‑carbon alloy with G3000/G11H18 iron castings and OE vane geometry, it is precision mill-balanced and fine-turned for reduced vibration. Geomet coating defends against corrosion; DTV ≤0.10 mm and lateral runout ≤0.50 mm.
