The DFC slotted Geomet-coated rotor for 1982–1985 Porsche 928 (left front) is a direct-fit replacement offering improved pad contact and heat dissipation. Built from hi‑carbon alloy with G3000/G11H18 castings and OE-style vanes, it’s precision mill-balanced and fine-turned to minimize vibration. Geomet corrosion protection and tight manufacturing tolerances—DTV ≤0.10 mm and lateral runout ≤0.50 mm—support consistent braking.
