Dynamic Friction 4804-39020 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4804-39020 GeoSpec Coated Brake Rotor is a premium OE-replacement plain disc brake rotor featuring DFC's proprietary corrosion-resistant coating technology. Engineered to match original equipment specifications, this rotor delivers reliable stopping performance and long-lasting durability straight out of the box.

DFC's GeoSpec coating applies a patented paint formula to every surface of the rotor — inside and out — forming a durable, attractive silver-gray finish that fights rust far more effectively than conventional paint or zinc coatings. The coating is designed to be safely swept away by the friction material during the bed-in process with no harmful effects on braking performance.

Key Features:

• Fully coated inside and out — superior corrosion protection over zinc and conventional paint coatings
• Premium G3000/G11H18 iron casting for exceptional strength, stability, and long-term durability
• OE vane configuration duplicated precisely for proper and maximum heat dissipation
• CNC-machined to tight tolerances for precise fit and consistent performance
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter, smoother stops
• 100% precision mill-balanced for vibration-free braking at any speed
• Ready to install — processed and shipped dry, no pre-cleaning required
• Sold individually (1 rotor per package)

The DFC GeoSpec line covers a broad range of foreign and domestic passenger car and light truck applications, providing a competitively priced, high-quality alternative to OEM parts. With no oily residue to clean and direct-fit OE specifications, installation is straightforward and efficient.
