Dynamic Friction 4804-54006 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4804-54006 is a GeoSpec fully coated plain disc brake rotor engineered as a direct OE replacement. Featuring DFC's proprietary GeoSpec coating, these rotors develop a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings — protecting the rotor completely, inside and out, before and after installation.

Each rotor is processed dry and ships ready to install with no pre-degreasing or cleaning required, saving significant time and labor during the brake job. The GeoSpec coating is designed not to contaminate friction or rotor surfaces, ensuring a proper bed-in and consistent wear characteristics from the first stop.

Key Features:

• Engineered with premium G3000/G11H18 cast iron for superior strength, stability, and durability
• Fully coated inside and out with GeoSpec rust-prevention coating — superior protection vs. zinc or conventional paint
• OE vane configuration for proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available
• 100% precision mill-balanced for smooth, vibration-free stops at any speed
