Dynamic Friction 4522-31148 GeoSpec Coated Plain Brake Rotor Kit

The Dynamic Friction Company (DFC) 4522-31148 is a pair of GeoSpec fully coated, plain/smooth brake rotors engineered as a direct OE replacement. Designed for everyday passenger car and light truck use, these rotors deliver reliable stopping performance right out of the box with no prep work required before installation.

GeoSpec Coating Advantage:

• Full inside-and-out corrosion protection — the proprietary GeoSpec coating covers the entire rotor surface, not just the hat and edges, providing superior rust resistance over standard zinc or conventional painted finishes
• Non-contaminating coating — formulated to prevent friction surface contamination during bed-in, ensuring proper pad seating and consistent wear characteristics from the start
• Ready to install — no pre-cleaning or degreasing required, saving installation time

Premium Construction:

• Cast from premium G3000 gray iron for optimal strength, thermal stability, and durability
• OE vane configuration duplicated precisely for maximum heat dissipation
• CNC-machined to tight tolerances for accurate fitment and smooth operation
• 100% precision mill-balanced to eliminate vibration and pedal pulsation at all speeds
• Non-directional surface finish promotes faster break-in and quieter, smoother stops

What's Included:

• 2x DFC GeoSpec Coated Smooth Brake Rotors (front or rear pair, position per application)

DFC GeoSpec rotors are engineered to meet the same form, fit, and function as original equipment brake rotors, making them an ideal choice for daily drivers seeking long-lasting, maintenance-free corrosion protection and dependable braking performance.
