Dynamic Friction 4822-31206 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction 4822-31206 DFC GeoSpec Coated Brake Rotor is a premium OE-replacement disc brake rotor engineered to meet or exceed original equipment specifications. Featuring Dynamic Friction Company's proprietary GeoSpec® coating, this plain-style vented rotor delivers superior corrosion resistance and a clean, professional appearance right out of the box.

Unlike rotors shipped with oil coatings, each GeoSpec rotor arrives processed dry and ready to install — no additional degreasing or preparation required. The durable silver-gray GeoSpec finish fights rust far better than conventional paint or zinc coatings, keeping the rotor protected throughout its service life.

Key Features:

• GeoSpec® Coating: Proprietary rust-resistant finish forms a durable silver-gray appearance — superior protection vs. conventional paint or zinc coatings
• Premium G3000/G11H18 Iron Castings: Engineered for strength, stability, and long-term durability
• OE Vane Configuration: Original Equipment vane geometry ensures proper and maximum heat dissipation
• CNC-Machined: Processed to the tightest tolerances available for precise, trouble-free fitment
• Non-Directional Brake Surface Finish: Promotes faster, more even brake pad bed-in and quieter, smoother stops

• 100% Inspected: Every rotor passes a full inspection station verifying all critical attributes against OE specifications
• Ready to Install: No pre-degreasing needed — saves time and reduces labor cost during installation
• Plain / Smooth Style: OE-style blank rotor surface for standard street and commuter use
• Vented Construction: Internal venting for improved thermal management and brake fade resistance
• 12-Month / 12,000-Mile Limited Warranty

The DFC GeoSpec program covers a broad range of foreign and domestic passenger cars and light trucks, and every rotor is built to match the original form, fit, and function of the factory brake rotor it replaces.
