Dynamic Friction 4822-31166 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4822-31166 is a GeoSpec fully coated plain (smooth) disc brake rotor engineered as a direct OE replacement. Featuring DFC's proprietary GeoSpec silver-gray rust-prevention coating applied inside and out, this rotor delivers superior corrosion resistance over conventional paint or zinc coatings — and arrives ready to install straight out of the box with no cleaning required.

GeoSpec Coating Advantage:

• Fully coated inside and out using high-quality rust-prevention coating for complete protection before and after installation
• Ready-to-install — processed and shipped dry, no degreasing or prep work needed, saving significant installation time
• Coating is brake-friendly — designed not to contaminate friction or rotor surfaces, ensuring proper bed-in and wear characteristics
• Durable silver-gray finish provides an attractive, OE-style appearance

Premium Construction & Performance:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• OE vane configuration duplicated precisely to ensure proper and maximum heat dissipation
• CNC-machined to the tightest tolerances for precise fitment
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional surface finish promotes faster brake pad bed-in and quieter, smoother stops
• Each rotor passes a 100% inspection station verifying all critical attributes meet OE specifications

Plain/Smooth rotor style is ideal for everyday commuting, normal street driving, and light towing applications. The DFC GeoSpec program covers foreign and domestic passenger cars and light trucks, making it one of the most complete coated rotor lineups available.
