Dynamic Friction 4804-63009 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4804-63009 is a GeoSpec fully coated plain disc brake rotor engineered as a direct OEM replacement. Featuring DFC's proprietary GeoSpec coating, this rotor is treated inside and out with a durable, attractive silver-gray finish that provides superior corrosion resistance over conventional paint or zinc coatings — keeping the rotor protected both before and after installation.

Each rotor is processed dry and shipped dry, meaning it arrives ready to install with no degreasing or additional preparation required. The GeoSpec coating is designed not to interfere with brake pad bed-in, as it is safely swept away by the friction material during normal break-in with no harmful effects.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• Original Equipment (OE) vane configuration for proper and maximum heat dissipation
• CNC-machined to the tightest tolerances for precise fit and quiet operation
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional surface finish promotes faster break-in and smoother, quieter stops
• GeoSpec coating provides superior corrosion protection over zinc and conventional paint
• Fully coated inside and out — ready to install, no cleaning required
