Dynamic Friction 4802-39009 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4802-39009 is a GeoSpec® fully coated plain (smooth) disc brake rotor engineered as a direct OEM replacement. Featuring DFC's proprietary GeoSpec® corrosion-protection coating, this rotor arrives ready to install straight out of the box — no pre-degreasing or additional preparation required.

GeoSpec® Coating Advantage:

• Forms a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings
• Completely coated inside and out for maximum corrosion resistance before and after installation
• Coating is safely swept away by friction material during normal break-in with no harmful effects

Precision Engineering:

• Premium G3000/G11H18 cast iron construction for superior strength, stability, and long-term durability
• CNC-machined to the tightest tolerances for precise OE form, fit, and function
• Original Equipment (OE) vane configuration ensures proper and maximum heat dissipation
• 100% precision cut and 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

Quality Assurance:

• Each rotor passes a 100% inspection station verifying all critical attributes meet OE specifications
• All vented rotors are electronically mill-balanced and corrected as needed
• Backed by a 1-year manufacturer warranty against defects in materials and workmanship

The DFC GeoSpec 4802-39009 plain rotor is ideal for everyday commuting and normal street driving, delivering quiet, smooth, confidence-inspiring stops without the need for any special installation prep.
