Dynamic Friction 4812-13017 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4812-13017 is a GeoSpec® fully coated plain disc brake rotor engineered as a direct OEM replacement. Designed to meet the same form, fit, and function as the original equipment rotor, this unit delivers reliable, quiet, and smooth braking performance right out of the box.

GeoSpec® Coating Technology:

DFC's proprietary GeoSpec® coating forms a durable, attractive silver-gray finish across the entire rotor — inside and out — providing superior rust and corrosion protection compared to conventional paint or zinc coatings. The coating is designed not to contaminate friction or rotor surfaces, ensuring a proper brake pad bed-in and consistent wear characteristics from day one.

Key Features:

• Fully coated inside and out for maximum corrosion resistance before and after installation
• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• OE vane configuration to ensure proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available for precise fit and performance
• 100% precision mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional finish to promote faster brake pad bed-in and quieter stops
• Ready to install — no additional pre-degreasing or preparation required, saving time and money during installation
• Backed by a 1-year manufacturer warranty against defects in materials and workmanship

The DFC 4812-13017 GeoSpec plain rotor is sold as a single unit and is built to meet or exceed OEM specifications, making it an excellent choice for everyday drivers seeking a quality, long-lasting brake rotor replacement with added corrosion protection.
