Dynamic Friction 4004-31064 DFC GeoSpec Coated Plain Brake Rotor Set

The Dynamic Friction Company (DFC) 4004-31064 is a complete brake rotor set featuring DFC's proprietary GeoSpec® coating — a patented corrosion-resistant finish engineered to outperform conventional paint and zinc coatings. These plain/smooth-style rotors deliver reliable OE-replacement performance with enhanced longevity and a clean, silver-gray appearance.

GeoSpec® Coating Technology:

• Patented coating forms a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings
• Rotors are processed dry, shipped dry, and ready to install right out of the box — no pre-degreasing required
• Superior corrosion protection extends rotor service life

Precision Engineering for Quiet, Smooth Stops:

• Machined to the tightest tolerances using CNC equipment for consistent performance
• Non-directional surface finish promotes faster, more even brake pad bed-in for quieter stops
• 100% precision mill-balanced to eliminate vibration at any speed
• OE vane configuration ensures proper heat dissipation

Quality Construction:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• Designed to meet the same form, fit, and function as OEM brake rotors
• 100% inspected — all critical attributes measured before leaving the facility
• Smooth/plain rotor style suitable for OE replacement and performance street driving

The DFC 4004-31064 is ideal for drivers seeking a direct OEM replacement that delivers improved corrosion resistance and long-lasting braking performance. No modifications required for installation.
