Dynamic Friction 4822-31012 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4822-31012 is a GeoSpec® fully coated plain (smooth) disc brake rotor engineered to deliver reliable, quiet, and corrosion-resistant braking performance. Designed as a direct OEM replacement, this rotor installs without modification and is ready to use straight out of the box.

GeoSpec® Coating Advantage:

• Superior rust protection — The patented GeoSpec® coating forms a durable, attractive silver-gray finish that fights corrosion far better than conventional paint or zinc coatings
• Fully coated inside and out — Complete coverage protects the rotor from the elements both before and after installation
• No pre-installation cleaning required — Processed dry and shipped dry, saving time and labor during the brake job
• Coating is friction-safe — The coating is safely swept away by the brake pad during break-in with no harmful contamination effects

Precision Engineering:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and long-term durability
• CNC-machined to the tightest tolerances available in the market
• 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
• OE vane configuration ensures proper heat dissipation for consistent braking performance
• All vented rotors are 100% electronically mill-balance inspected before shipment

OEM Form, Fit, and Function:

• Designed to match the same form, fit, and function as the original equipment brake rotor
• No modifications required for installation
• Quality tested to ensure long-lasting performance

The DFC GeoSpec® rotor program covers over 1,400 SKUs across a wide range of foreign and domestic passenger cars and light trucks, making it one of the most comprehensive coated rotor programs available.
