Dynamic Friction 4522-63125 GeoSpec Coated Slotted Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-63125 is a GeoSpec Coated Slotted Disc Brake Rotor engineered to deliver reliable, high-performance braking for everyday driving and performance street use. Part of DFC's premium GeoSpec line, this rotor combines a corrosion-resistant coating with a performance-oriented slotted surface design.

GeoSpec Coating Technology:

• Specially formulated patented paint forms a durable, attractive silver-gray finish
• Fights rust and corrosion far better than conventional paint or zinc coatings
• Shipped dry and ready to install — no pre-cleaning or degreasing required
• Coating is safely swept away by brake pad friction material during normal break-in with no harmful effects

Slotted Rotor Design:

• Slots continuously channel away brake dust, road debris, and gases from the rotor surface
• Reduces pad glazing for consistent, fade-resistant braking performance
• Enhances pad bite for improved stopping distances, especially in wet or demanding conditions

Premium Construction:

• Cast from premium G3000/G11H18 iron for exceptional strength, stability, and long-term durability
• CNC-machined to the tightest tolerances available for precise fitment
• OE (Original Equipment) vane configuration ensures maximum and proper heat dissipation
• 100% precision cut and mill-balanced for smooth, vibration-free stopping at any speed
• Non-directional rotor finish promotes faster, more even brake pad bed-in and quieter stops
• Built to OEM specifications for direct, no-modification installation

The DFC GeoSpec 4522-63125 slotted rotor is an excellent upgrade or direct replacement for drivers seeking improved corrosion resistance and enhanced braking performance over standard OE rotors.
