Dynamic Friction 4822-31118 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4822-31118 GeoSpec Coated Plain Brake Rotor is a precision-engineered OE-replacement disc brake rotor featuring DFC's signature GeoSpec fully coated finish. Designed to deliver quiet, smooth, and reliable stopping power, this rotor is built to meet or exceed original equipment specifications right out of the box.

GeoSpec® Coating Technology:

Unlike conventional paint or zinc-coated rotors, the GeoSpec coating forms a durable, attractive silver-gray finish that provides superior corrosion resistance across the entire rotor — inside and out. Each rotor is processed dry, shipped dry, and arrives ready to install with no pre-cleaning required. The coating is safely swept away by the friction material during the break-in process with no harmful effects to brake performance.

Key Features:

• Premium G3000/G11H18 iron casting for superior strength, stability, and long-term durability
• CNC-machined to the tightest tolerances for precise fitment and consistent performance
• 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
• OE vane configuration ensures proper and maximum heat dissipation
• Fully coated inside and out — superior corrosion protection over zinc or conventional paint
• 100% inspected at the factory — each rotor passes a full inspection station verifying all critical attributes meet OE specifications
• Smooth/plain rotor style — ideal for OE replacement and everyday driving

The DFC GeoSpec rotor program covers approximately 1,400+ SKUs for foreign and domestic passenger cars and light trucks, making it one of the most comprehensive coated rotor programs available. The 4822-31118 delivers a factory-quality brake upgrade with enhanced corrosion protection and a clean, finished appearance.
