Dynamic Friction 4004-46034 DFC GeoSpec Coated Plain Brake Rotor Set

The Dynamic Friction Company (DFC) 4004-46034 is a complete front and rear plain/smooth brake rotor set finished with DFC's proprietary GeoSpec® corrosion-protection coating. Engineered as a direct OE replacement, this set delivers reliable, quiet braking performance right out of the box.

The GeoSpec® coating forms a durable silver-gray finish that fights rust far more effectively than conventional paint or zinc coatings, keeping rotors protected from the factory through installation and beyond. Each rotor is processed dry and shipped dry — no degreasing or additional prep is required before mounting, saving time and effort during installation.

Key Features:

• Proprietary GeoSpec® coating provides superior corrosion resistance over zinc and conventional paint coatings
• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• OE vane configuration maintained for proper and maximum heat dissipation
• CNC-machined to tight tolerances for precise fit and consistent braking
• 100% precision mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional surface finish promotes faster, more even brake pad bed-in for quieter stops
• Each rotor passes a 100% electronic inspection station measuring critical attributes to OE specifications
• Processed dry and shipped dry — ready to install straight from the box
• Designed to meet or exceed OEM form, fit, and function
• Smooth/plain rotor style for OE-equivalent everyday street performance

The DFC GeoSpec coating is validated to withstand 400 hours of salt-spray testing per automotive manufacturer corrosion test methods, making it one of the most durable OE-replacement rotor coatings available. This 4-wheel set is an ideal upgrade for normal commuting, performance street driving, towing, and light off-road use.
