Dynamic Friction 9004-46027 DFC GEOMET Coated Plain Disc Brake Rotor Set

The Dynamic Friction Company (DFC) 9004-46027 is a GEOMET-coated plain (blank) disc brake rotor set engineered as a direct OE replacement. Built with high-carbon alloy iron formulations, these rotors deliver superior noise dampening, increased thermal conductivity, and long-lasting durability compared to standard iron discs.

At the core of this rotor's corrosion resistance is the genuine GEOMET® coating, applied uniformly across the entire rotor surface—including the hat, vanes, and edges. GEOMET provides superior protection over conventional zinc or paint coatings, and is processed dry and ready to install with no degreasing required. The coating is safely swept away from the friction surface during normal break-in.

Key Features:

• High-Carbon Alloy Construction – Carbon, chromium, and molybdenum formulations enhance noise dampening, strength, and thermal conductivity
• GEOMET® Corrosion Protection – Superior rust resistance over zinc or conventional paint coatings; ready to install out of the box
• 100% Precision Mill-Balanced – Ensures smooth, vibration-free stopping at any speed
• CNC Machined to Tight Tolerances – Disc Thickness Variation (DTV) max .010mm; Lateral Runout max .050mm
• Fine-Turned Finish (1.6 RMS) – Promotes faster, more even brake pad bed-in for quieter, smoother stops
• OE Vane Configuration – Maintains proper heat dissipation consistent with original equipment design
• 100% Electronic Inspection – Each rotor is tested across 20+ quality attributes to confirm OE specification compliance
• Limited Warranty – Covered by DFC's 12-month / 12,000-mile limited warranty

The DFC 9004-46027 GEOMET rotor set is engineered to match the form, fit, and function of the original equipment rotors it replaces, making it an ideal choice for daily driving, commuting, and moderate performance street use.
