Dynamic Friction 4812-55087 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4812-55087 is a GeoSpec® Coated Plain Disc Brake Rotor engineered as a direct OE replacement. GeoSpec® coating uses a patented paint formulation to form a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings — inside and out.

Key Features:

• Fully coated inside and out — superior corrosion protection over zinc and conventional painting
• Premium G3000 iron casting for strength, stability, and long-term durability
• OE vane configuration duplicated precisely for proper and maximum heat dissipation
• CNC-machined to the tightest tolerances for an exact OE fit
• Non-directional surface finish promotes faster, more even brake pad bed-in with quieter, smoother stops
• 100% precision mill-balanced for vibration-free stopping at any speed
• Ready to install — processed dry, shipped dry, no cleaning or prep required before installation
• Coating is brake-safe — safely swept away by friction material during bed-in with no harmful effects

DFC GeoSpec rotors are engineered to meet or exceed original equipment specifications, offering complete corrosion protection before and after installation. The time-saving, no-prep design means a typical brake job takes just 1.25 to 2.5 hours per axle.
