Dynamic Friction 4814-40117 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4814-40117 is a GeoSpec® Fully Coated Plain Disc Brake Rotor engineered to deliver OE-quality braking performance with superior corrosion resistance. Designed as a direct-fit OEM replacement, this rotor installs without modification and is ready to use straight out of the box—no degreasing or pre-cleaning required.

GeoSpec® Coating Technology:

Unlike standard rotors protected only by zinc plating or conventional paint, the GeoSpec® coating forms a durable, attractive silver-gray finish that provides superior rust protection both before and after installation. The full rotor body—inside and out—is completely coated, protecting the rotor from the elements throughout its service life. The coating is safely swept away by the friction material during normal break-in with no harmful effects on brake performance.

Key Features:

• Premium G3000/G11H18 iron casting for superior strength, stability, and long-term durability
• CNC-machined to tight tolerances for precise fit and consistent performance
• OE vane configuration replicates original equipment design for maximum and proper heat dissipation
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter stops
• 100% mill-balanced using electronic mill-balance process to eliminate vibration and pedal pulsation at any speed
• 100% inspected — each rotor passes a full inspection station verifying all critical attributes meet OE specifications
• Ready to install — shipped dry with no additional preparation needed, saving time during installation
• Smooth/Plain rotor style — ideal for OE replacement and everyday commuting

The Dynamic Friction 4814-40117 is engineered to meet the same form, fit, and function as the original equipment brake rotor it replaces, making it an excellent choice for drivers seeking a reliable, long-lasting OEM-quality upgrade with enhanced corrosion protection.
