Dynamic Friction 4814-21013 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4814-21013 is a GeoSpec fully coated plain (smooth/blank) disc brake rotor engineered as a direct OEM replacement for passenger cars and light trucks. Built on DFC's GeoSpec platform, this rotor delivers superior corrosion protection and a clean, ready-to-install experience right out of the box.

GeoSpec Coating Technology:

• Completely coated inside and out with a patented rust-prevention paint that forms a durable, attractive silver-gray finish
• Fights rust far better than conventional paint or zinc coatings for longer rotor life
• Coating is processed dry and shipped dry — no cleaning required before installation
• Designed not to contaminate friction or rotor surfaces, ensuring proper brake bed-in and consistent wear characteristics
• The GeoSpec finish is safely and cleanly swept away by the friction material during initial bedding with no harmful effects

Premium Construction:

• Engineered and manufactured with premium G3000 iron castings that duplicate precise OEM vane configurations and fitment
• CNC-machined to tight tolerances for exact form, fit, and function
• 100% precision mill-balanced for smooth, vibration-free stopping at any speed
• Non-directional surface finish promotes faster break-in and smoother stops
• Each rotor passes a 100% electronic inspection measuring over 20 attributes to ensure OE-spec compliance
