Dynamic Friction 4522-31076 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4522-31076 is a GeoSpec Coated Plain Disc Brake Rotor engineered as a direct OE replacement. Featuring DFC's proprietary GeoSpec coating, this rotor delivers a durable, attractive silver-gray finish that provides superior corrosion resistance compared to conventional paint or zinc coatings — protecting the hat, edges, and cooling vanes from rust and environmental damage.

Key Features:

• GeoSpec Corrosion Protection: Patented coating fights rust far better than conventional paint or zinc coatings, maintaining a clean appearance and extended service life
• Premium G3000/G11H18 Iron Casting: Engineered for superior strength, stability, and long-term durability
• OE Vane Configuration: Duplicates original equipment vane geometry for maximum heat dissipation and proper airflow
• CNC-Machined to Tight Tolerances: Ensures precise fitment and consistent braking performance
• Non-Directional Finish: Promotes faster, more even brake pad bed-in and quieter, smoother stops
• 100% Mill-Balanced: Precision electronic mill-balance process eliminates vibration at any speed
• Ready to Install: Processed and shipped dry — no pre-cleaning or degreasing required, saving time during installation
• 100% OE Specification Inspection: Every rotor passes a full quality inspection measuring all critical attributes before leaving the facility

The DFC GeoSpec rotor line spans over 1,400 SKUs, covering a wide range of foreign and domestic passenger cars and light trucks. This plain/blank rotor surface style is ideal for everyday commuting and street use, delivering reliable stopping power and a consistent pedal feel right out of the box.
