The DFC GeoSPEC coated rotor for 2000–2008 Audi A4 (USA/Canada) rear applications is an OE-style replacement offering improved longevity and corrosion resistance. It arrives ready-to-install with a non-directional finish to speed break-in, is precision cut and mill-balanced for vibration-free stopping, and uses premium G3000/G11H18 iron castings protected by a coating superior to zinc-based treatments.
