Dynamic Friction 4804-31049 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4804-31049 is a GeoSpec Coated Plain (smooth) Disc Brake Rotor engineered to deliver OE-quality braking performance with superior corrosion resistance. Designed to match the exact form, fit, and function of your original equipment rotor, this is a direct-fit replacement requiring no modifications.

DFC's proprietary GeoSpec® coating forms a durable, attractive silver-gray finish that fights rust and corrosion far more effectively than conventional paint or zinc coatings. Each rotor ships dry and is ready to install straight out of the box — no pre-degreasing or cleaning required, saving valuable time during installation.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for exceptional strength, stability, and long-term durability
• GeoSpec® patented coating provides superior rust and corrosion resistance over zinc or conventional paint finishes
• OE vane configuration ensures proper and maximum heat dissipation during braking
• CNC-machined to the tightest tolerances available for precise fitment
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter stops
• Passes a 100% inspection station verifying all critical attributes meet OE specifications
• Plain (smooth) rotor style — ideal for daily driving and standard OE replacement applications
• Ships dry — no additional preparation needed prior to installation

The Dynamic Friction GeoSpec series covers a comprehensive range of passenger cars and light trucks, providing a reliable, cost-effective brake rotor upgrade over standard uncoated replacements.
