Dynamic Friction 4802-47039 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4802-47039 GeoSpec Coated Brake Rotor is a plain (smooth/blank) disc brake rotor engineered to deliver OEM-equivalent stopping performance with superior corrosion protection. Part of DFC's industry-leading GeoSpec coated rotor program, this rotor is fully coated inside and out with a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings.

Each GeoSpec rotor is precision-machined at DFC's state-of-the-art facilities to the tightest tolerances available, then finished with a non-directional surface to promote faster, more even brake pad bed-in for quieter, smoother stops. All vented rotors undergo 100% electronic mill-balancing to eliminate vibration at any speed, and each unit passes a full inspection station to verify it meets OE specifications before shipment.

A key advantage of the GeoSpec coating is its ready-to-install design — rotors are processed dry, shipped dry, and require no degreasing or pre-cleaning before installation. The coating is safely and cleanly swept away by the friction material during normal brake bed-in, with no harmful effects on brake performance.

Key Features:

• Fully coated inside and out with GeoSpec silver-gray rust-prevention coating — superior to conventional paint or zinc finishes
• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• Original Equipment (OE) vane configuration for proper and maximum heat dissipation
• CNC-machined to the tightest tolerances for precise fitment
• 100% precision cut and mill-balanced for smooth, vibration-free stopping at any speed
• Non-directional finish promotes faster brake pad bed-in and quieter stops
• Ready to install straight out of the box — no cleaning or degreasing required
• Designed to meet the same form, fit, and function as OEM brake rotors
• 100% inspected at the factory to ensure OE specification compliance

The DFC 4802-47039 is part of the GEO-KIT 4000 (4802) series, which pairs GeoSpec coated rotors with DFC brake pads. Note: hardware is not included with the 4802 series. This rotor is the ideal choice for drivers seeking a direct OEM replacement with enhanced corrosion resistance and long-lasting, reliable braking performance.
