Dynamic Friction 4522-31037 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4522-31037 is a GeoSpec Coated Plain (Smooth) Disc Brake Rotor designed as a direct OE replacement. Engineered to match original equipment specifications for form, fit, and function, this rotor delivers reliable stopping performance with enhanced corrosion resistance straight out of the box.

GeoSpec Coating Technology:

DFC's proprietary GeoSpec coating forms a durable, attractive silver-gray finish that fights rust and corrosion far more effectively than conventional paint or zinc coatings. The entire rotor—inside and out—is fully coated for complete protection before and after installation. The coating is designed not to contaminate friction surfaces, ensuring a proper brake pad bed-in and consistent wear characteristics over the life of the rotor.

Key Features:

• Premium G3000/G11H18 iron casting for superior strength, stability, and long-term durability
• OE vane configuration duplicates original equipment design for proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available for precise fitment
• 100% precision mill-balanced for smooth, vibration-free stops at any speed
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter operation
• 100% inspected — each rotor passes a full inspection station verifying all critical attributes to OE specifications
• Ready to install — processed and shipped dry, no pre-cleaning or degreasing required
• Plain/smooth rotor face for OE-equivalent everyday street and commuter driving

The DFC GeoSpec program covers more than 1,400 SKUs across domestic and import passenger cars and light trucks, making it one of the most comprehensive coated rotor programs available. Each rotor is sold individually.
