Dynamic Friction 4522-31028 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-31028 GeoSpec Coated Plain Brake Rotor is a premium OE-replacement disc brake rotor engineered for reliable, quiet, and smooth stopping performance. Featuring DFC's proprietary GeoSpec® corrosion-protection coating, this rotor delivers superior rust resistance and is ready to install straight out of the box.

GeoSpec® Coating Technology:

• Fully coated inside and out with a patented paint formula that forms a durable, attractive silver-gray finish
• Fights rust and corrosion far better than conventional paint or zinc coatings
• Coating is designed not to contaminate friction or rotor surfaces, ensuring proper brake pad bed-in and wear characteristics
• No additional pre-degreasing or cleaning required before installation — saves time and money

Precision Engineering:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• CNC-machined to the tightest tolerances available for a precise OE-spec fit
• Original Equipment (OE) vane configuration ensures proper and maximum heat dissipation
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter stops
• 100% precision cut and mill-balanced for smooth stopping and zero vibration at any speed

Quality Assurance:

• Each rotor passes a 100% electronic inspection station measuring over 20 critical attributes
• Designed to meet the same form, fit, and function as OEM brake rotors
• No modifications required for installation

The DFC GeoSpec line covers a wide range of foreign and domestic passenger car and light truck applications, making it one of the most comprehensive coated rotor programs available.
