Dynamic Friction 4822-31225 GeoSpec Coated Cross-Drilled Disc Brake Rotor

The Dynamic Friction Company (DFC) 4822-31225 is a GeoSpec Coated Cross-Drilled Disc Brake Rotor engineered to deliver reliable, OE-quality stopping power with enhanced corrosion resistance. Sold individually, this rotor is designed to meet the same form, fit, and function as the original equipment brake rotor it replaces.

GeoSpec Coating Technology:

DFC's patented GeoSpec coating forms a durable, attractive silver-gray finish that fights rust far more effectively than conventional paint or zinc coatings. Each rotor is processed dry and shipped dry — ready to install with no additional cleaning or preparation required. The coating is safely swept away by the friction material during normal brake operation with no harmful effects.

Cross-Drilled Design:

• Cross-drilled holes reduce heat buildup on the rotor surface for improved thermal management
• Drilled holes are chamfered to minimize the potential for stress cracking
• Enhanced bite and shorter stopping distances, especially in wet weather conditions

Precision Engineering:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• CNC-machined to the tightest tolerances available
• OE vane configuration for proper and maximum heat dissipation
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional finish promotes faster brake pad bed-in and quieter, smoother stops
• All vented rotors are 100% electronically inspected and corrected for balance

The DFC 4822-31225 GeoSpec Coated Drilled Rotor is an ideal upgrade or direct replacement for drivers seeking improved corrosion resistance and enhanced braking performance over a standard blank rotor.
