Dynamic Friction 4004-55005 DFC GeoSpec Coated Plain Brake Rotor Set

The Dynamic Friction Company 4004-55005 is a complete GeoSpec coated plain brake rotor set designed as a direct OE replacement. DFC GeoSpec Coated Brake Rotors are built with the same form, fit, and function as your original rotors—delivering reliable, quiet, and vibration-free stopping power right out of the box.

GeoSpec Coating Technology:

Unlike conventional paint or zinc coatings, DFC's proprietary GeoSpec coating forms a durable, attractive silver-gray finish that provides superior corrosion resistance. Each rotor is processed dry, shipped dry, and ready to install—no pre-degreasing or surface preparation required, saving significant time and labor during installation. The coating is safely and gradually swept away by the friction material during normal break-in with no harmful effects.

Key Features:

• Premium G3000/G11H18 iron casting for superior strength, stability, and durability
• OE vane configuration ensures proper and maximum heat dissipation
• CNC-machined to the tightest tolerances for precise fitment
• 100% precision mill-balanced for smooth, vibration-free stopping at any speed
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter stops
• 100% inspected at the factory to verify all critical OE specifications are met
• Superior corrosion protection over conventional zinc or painted coatings
• Ready to install — no additional preparation needed
