Dynamic Friction 4822-31112 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4822-31112 is a GeoSpec Coated plain (smooth/blank) disc brake rotor engineered as a direct OE replacement. DFC's GeoSpec coating program applies a proprietary patented paint finish to form a durable, attractive silver-gray surface that provides superior corrosion protection compared to conventional paint or zinc coatings — covering the rotor completely inside and out.

Key Features:

• Fully coated inside and out — GeoSpec coating protects the entire rotor surface before and after installation, eliminating surface rust and pre-installation corrosion
• Ready to install — processed dry and shipped dry; no cleaning or degreasing required prior to installation
• Coating is brake-safe — designed not to contaminate friction surfaces, ensuring proper bed-in and consistent wear characteristics
• Premium G3000/G11H18 iron casting — delivers excellent strength, stability, and long-term durability
• OE vane configuration — duplicates original equipment vane geometry for maximum heat dissipation
• CNC-machined to tight tolerances — ensures precise fitment and optimal braking performance
• Non-directional surface finish — promotes faster, more even brake pad bed-in for quieter, smoother stops
• 100% mill-balanced — electronically balanced to eliminate vibration at any speed
• Plain / blank rotor style — smooth face design suitable for normal commute, performance street, towing, and light off-road use

DFC GeoSpec rotors are engineered to meet or exceed OEM specifications and are part of one of the most complete coated rotor programs available, with coverage spanning foreign and domestic passenger cars and light trucks. Each rotor ships individually and is ready for immediate installation.
