Dynamic Friction 4524-40006 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4524-40006 GeoSpec Coated Plain Disc Brake Rotor delivers OE-quality stopping performance with an industry-leading corrosion-resistant coating. Engineered as a direct OEM replacement, this plain-style brake rotor is fully coated inside and out with DFC's patented silver-gray paint finish, providing superior rust protection compared to conventional zinc or paint coatings.

Each GeoSpec rotor arrives processed dry and ready to install — no degreasing or pre-cleaning required. The coating is safely swept away by the friction material during the bed-in process with no harmful effects, saving time and money during installation.

Key Features:

• Patented GeoSpec Coating: Durable silver-gray finish fights rust far better than conventional paint or zinc coatings
• Premium G3000/G11H18 Iron Castings: Engineered for superior strength, stability, and long-term durability
• OE Vane Configuration: Duplicates original equipment vane geometry for proper and maximum heat dissipation
• CNC-Machined: Precision-machined to the tightest tolerances available
• 100% Precision Mill-Balanced: Ensures smoother stopping and zero vibration at any speed
• Non-Directional Finish: Promotes faster brake pad bed-in and quieter, smoother stops
• Ready to Install: Ships dry with no additional preparation needed — no oil-covered rotor to clean
• 100% OE Spec Inspected: Each rotor passes a full inspection station measuring all critical attributes before shipment
