The DFC Geomet-coated drilled rear rotor for 2005–2023 Porsche Cayman is a hi‑carbon alloy replacement engineered to handle heat and surface corrosion over prolonged use. Premium G3000/G11H18 iron castings and OE vane configuration help dissipate heat, and 100% precision mill-balancing reduces vibration. A fine-turned 16 RMS finish aids pad break-in while Geomet coating protects against corrosion; DTV 0.10 mm and runout 0.50 mm are specified.
