Dynamic Friction 4822-11021 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4822-11021 GeoSpec Coated Plain Disc Brake Rotor is a premium OE-replacement brake rotor engineered for reliable, corrosion-resistant stopping performance. Featuring DFC's patented GeoSpec coating, this rotor develops a durable, attractive silver-gray finish that provides superior rust protection compared to conventional paint or zinc coatings — inside and out.

Each rotor is cast from premium G3000/G11H18 iron and CNC-machined to tight tolerances, replicating the precise original equipment vane configuration for optimal heat dissipation. A 100% electronic mill-balance inspection ensures smooth, vibration-free stopping at any speed. The non-directional rotor finish promotes faster, more even brake pad bed-in for quieter and smoother stops right from the start.

Key Features:

• GeoSpec patented coating provides superior corrosion protection over zinc and conventional paint — rotor is fully coated inside and out
• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• OE vane configuration ensures proper and maximum heat dissipation
• CNC-machined to the tightest tolerances for precise OEM form, fit, and function
• 100% precision mill-balanced for smooth, vibration-free braking at all speeds
• Non-directional surface finish promotes faster brake pad bed-in and quieter stops
• Ready to install — processed dry, shipped dry, no pre-cleaning or degreasing required
• Plain/smooth rotor style for OE replacement use

The DFC GeoSpec coating is designed not to contaminate friction surfaces during bed-in, so the coating is safely swept away by the brake pads with no harmful effects. This rotor is built to meet the same form, fit, and function as your original equipment brake rotor, making it an ideal direct replacement for everyday street driving.
