Dynamic Friction 4802-39008 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4802-39008 is a GeoSpec® Coated Plain Brake Rotor engineered to deliver OE-quality stopping performance with superior corrosion protection. Part of DFC's GEO-KIT 4000 series, this rotor features a fully coated design — processed dry, shipped dry, and ready to install straight out of the box with no cleaning required.

The proprietary GeoSpec® coating forms a durable, attractive silver-gray finish that fights rust far more effectively than conventional paint or zinc coatings, protecting the rotor both before and after installation. Because the coating is designed not to contaminate friction or rotor surfaces, it is simply and safely swept away by the brake pad during the normal bed-in process — with no harmful effects on performance or wear characteristics.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• Fully coated inside and out with GeoSpec® rust prevention coating for superior corrosion protection over zinc or conventional paint
• OE vane configuration duplicates original equipment design to ensure proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available for precise fit and function
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional surface finish promotes faster break-in and quieter, smoother stops
• Meets or exceeds OE specifications — 100% inspected for all critical attributes before shipping
• Ready to install — no pre-cleaning, degreasing, or additional preparation needed

Designed as a direct OE replacement, the DFC 4802-39008 plain rotor is part of the GeoSpec program — one of the most complete coated rotor lines in the industry, covering a wide range of domestic and foreign passenger car and light truck applications.
