Dynamic Friction 4522-31172 GeoSpec Coated Drilled Disc Brake Rotor

The Dynamic Friction Company 4522-31172 is a GeoSpec Coated Cross-Drilled Disc Brake Rotor engineered to deliver OE-quality braking performance with enhanced corrosion resistance. Designed as a direct-fit replacement, this rotor ships ready to install with no additional prep work required.

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 coating is safely swept away by the friction material during normal break-in, leaving no harmful residue or effects on braking performance.

Key Features:

• Premium G3000/G11H18 iron castings for maximum strength, stability, and long-term durability
• Cross-drilled holes for improved heat dissipation, gas venting, and pad bite during aggressive driving
• OE vane configuration to ensure proper and maximum heat dissipation under all driving conditions
• CNC-machined to the tightest tolerances for precise fitment and consistent braking feel
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional surface finish to promote faster brake pad bed-in and quieter, smoother stops
• Superior corrosion protection over conventional zinc and paint coatings
• Processed dry and shipped dry — no cleaning required before installation

The 4522-31172 is designed to meet or exceed OEM specifications for form, fit, and function, making it a reliable upgrade or direct replacement for worn factory rotors. Whether used for everyday commuting or performance street driving, this DFC GeoSpec rotor delivers consistent, confident stopping power.
