Dynamic Friction 4802-31090 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4802-31090 GeoSpec Coated Plain Brake Rotor is a premium OE-replacement disc brake rotor engineered for reliable, quiet, and smooth stopping performance. Built to meet the same form, fit, and function as your original equipment rotor, it is an ideal direct-swap replacement requiring no modifications.

GeoSpec Coating Technology:

Each rotor is treated with DFC's proprietary GeoSpec corrosion-resistant coating, which forms a durable, attractive silver-gray finish that provides superior rust protection compared to conventional paint or zinc coatings. The coating is fully applied inside and out, meaning this rotor arrives processed dry, shipped dry, and ready to install — no pre-degreasing or cleaning required, saving time and money at installation.

Key Features:

• Premium G3000/G11H18 iron casting for superior strength, stability, and long-term durability
• OE vane configuration ensures proper and maximum heat dissipation during braking
• Non-directional surface finish promotes faster, more even brake pad bed-in for quieter and smoother stops
• CNC-machined to the tightest tolerances available for precise fit and consistent performance
• 100% precision cut and mill-balanced for vibration-free stopping at any speed
• 100% inspected — each rotor passes a full quality inspection to verify all critical attributes meet OE specifications
• Superior corrosion protection over conventional zinc or painted coatings
• Ready to install — no additional preparation needed, reducing brake job time
