Dynamic Friction 4822-63138 GeoSpec Coated Cross-Drilled Disc Brake Rotor

The Dynamic Friction Company (DFC) 4822-63138 GeoSpec Coated Drilled Brake Rotor delivers a premium OE-replacement upgrade engineered for reliable, consistent stopping performance. Built from premium G3000/G11H18 iron castings, this rotor is designed to match the exact form, fit, and function of your original equipment brake rotor while adding the durability benefits of DFC's proprietary GeoSpec coating technology.

The GeoSpec coating forms a durable, attractive silver-gray finish that provides superior rust and corrosion protection compared to conventional paint or zinc coatings. Unlike oil-coated rotors, GeoSpec rotors are processed dry and shipped dry — they are ready to install right out of the box with no cleaning or prep required, saving time during installation. The coating is safely swept away by the brake pad friction material during normal break-in with no harmful effects on braking performance.

Cross-drilled holes enhance brake cooling and help sweep away gas, heat, and debris from the rotor surface, improving bite and fade resistance under demanding driving conditions. Each rotor is CNC-machined to the tightest tolerances and features a non-directional surface finish to promote a faster, more even brake pad bed-in and quieter, smoother stops. All vented rotors are 100% mill-balanced for vibration-free performance at any speed.
