Dynamic Friction 4822-31179 GeoSpec Coated Plain Disc Brake Rotor Kit

The Dynamic Friction Company 4822-31179 is a GeoSpec fully coated plain (smooth) disc brake rotor engineered as a direct OE replacement. DFC's GeoSpec coating delivers a durable, attractive silver-gray finish that provides superior corrosion resistance compared to conventional paint or zinc coatings, protecting the rotor completely — inside and out — before and after installation.

Each GeoSpec rotor arrives processed dry, shipped dry, and ready to install with no cleaning or pre-treatment required. The coating is designed not to contaminate friction or rotor surfaces, ensuring proper brake pad bed-in and consistent wear characteristics from the very first stop.

Key Features:

• GeoSpec fully coated — complete corrosion protection on all surfaces, including hat and vanes
• Premium G3000/G11H18 iron castings for superior strength, stability, and long-term durability
• OE vane configuration to ensure proper and maximum heat dissipation
• CNC-machined to the tightest tolerances for precise fit and consistent performance
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional finish to promote faster brake pad break-in and quieter, smoother stops
• 100% inspected at the factory — all critical attributes verified to meet OE specifications
• Plain/smooth rotor surface — ideal for everyday commuting and OE-style replacement
• Ready to install — no additional preparation or cleaning required

The Dynamic Friction 4822-31179 is part of DFC's GeoSpec coated rotor program, one of the industry's most complete vehicle coverage programs for domestic and foreign passenger cars and light trucks. It is designed to meet the same form, fit, and function as the original equipment brake rotor it replaces.
