Dynamic Friction 4522-63128 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-63128 is a GeoSpec Coated Plain (smooth/blank) disc brake rotor engineered to deliver reliable, OE-quality stopping performance with superior corrosion resistance. Featuring DFC's proprietary GeoSpec coating, this rotor forms a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings — keeping your brakes protected before, during, and after installation.

Key Features:

• Full GeoSpec Coating: Completely coated inside and out with a high-quality rust-prevention finish that outperforms conventional zinc or painted coatings
• Premium G3000/G11H18 Iron Castings: Engineered for superior strength, stability, and long-lasting durability
• OE Vane Configuration: Matches original equipment vane design to ensure proper and maximum heat dissipation
• CNC-Machined to Tight Tolerances: Precision machining ensures correct fitment and smooth braking performance
• 100% Mill-Balanced: Every vented rotor is precision cut and electronically mill-balanced for smoother stopping and zero vibration at any speed
• Non-Directional Finish: Promotes faster, more even brake pad bed-in for quieter, smoother stops right away
• Ready to Install: Processed dry and shipped dry — no additional pre-degreasing or cleaning required before installation
• 100% Inspected: Each rotor passes a full inspection station measuring all critical attributes to confirm OE specification compliance

The DFC GeoSpec coating is engineered not to contaminate friction or rotor surfaces, ensuring a proper braking bed-in and consistent wear characteristics over the life of the rotor. Designed to meet the same form, fit, and function as OEM brake rotors, the 4522-63128 is a direct-replacement disc brake rotor built for everyday commuting, performance street use, and demanding driving conditions.
