Dynamic Friction 4004-21018 DFC GeoSpec Coated Plain Disc Brake Rotor Set

The Dynamic Friction Company (DFC) 4004-21018 GeoSpec Coated Plain Brake Rotors deliver reliable, OE-quality stopping performance with enhanced corrosion resistance. Part of DFC's GeoSpec coated rotor program, these blank/plain rotors are engineered to meet or exceed original equipment specifications for a direct, no-hassle replacement.

GeoSpec® Coating Technology:

Each rotor is treated with DFC's patented GeoSpec® coating, forming a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings. The coating is applied fully — inside and out — protecting rotors from the elements both before and after installation.

Key Features:

• Ready to Install: Processed dry and shipped dry — no additional pre-degreasing or cleaning required, saving time and money during installation
• Premium G3000/G11H18 Iron Castings: Engineered for superior strength, stability, and long-lasting durability
• OE Vane Configuration: Duplicates the original equipment vane geometry to ensure proper and maximum heat dissipation
• CNC-Machined to Tight Tolerances: Ensures precise fit, form, and function matching OEM brake rotors
• 100% Mill-Balanced: Precision cut and electronically mill-balanced for smooth, vibration-free stopping at any speed
• Non-Directional Finish: Promotes faster brake pad bed-in and smoother stops right from the start
• 100% Inspected: Every rotor passes a full electronic inspection measuring all critical attributes before leaving the facility
• Superior Corrosion Protection: Outperforms zinc and conventional paint coatings for extended rotor life

The DFC GeoSpec 4004-21018 rotor set is ideal for everyday commuting and normal driving conditions, delivering quiet, smooth braking performance with the confidence of OEM-level engineering. Backed by a manufacturer's warranty against defects in materials and workmanship.
