Dynamic Friction 4812-01009 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4812-01009 is a GeoSpec fully coated plain/smooth disc brake rotor engineered as a direct OEM replacement. The proprietary GeoSpec coating forms a durable, attractive silver-gray finish that fights rust and corrosion far more effectively than conventional paint or zinc coatings — protecting the rotor both before and after installation.

Each rotor is CNC-machined at state-of-the-art facilities to the tightest tolerances available, then finished with a non-directional surface to promote faster, more even brake pad bed-in and consistently smooth, quiet stops. All vented rotors are 100% inspected for balance and corrected using an electronic mill-balance process to eliminate vibration at any speed.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• GeoSpec fully coated inside and out — superior corrosion resistance over zinc or conventional paint coatings
• OE vane configuration duplicated precisely for proper and maximum heat dissipation
• CNC-machined to tight tolerances for accurate fit and reliable performance
• Non-directional finish promotes faster break-in and smoother, quieter stops
• 100% mill-balanced for zero vibration at any speed
• Ready to install — no pre-degreasing or additional preparation required
• Designed to meet the same form, fit, and function as OEM brake rotors
• No modifications required for installation
• Includes 1-year warranty against manufacturer defects

DFC GeoSpec coated rotors are processed dry and shipped dry, saving time and money during installation. The GeoSpec coating is designed not to contaminate friction or rotor surfaces, ensuring proper braking bed-in and wear characteristics right from the first stop.
