Dynamic Friction 9004-27012 Hi-Carbon Alloy GEOMET Coated Disc Brake Rotor Set - Plain

The Dynamic Friction Company 9004-27012 is a Hi-Carbon Alloy GEOMET Coated plain (blank) disc brake rotor set engineered to meet or exceed OEM specifications. Designed as a direct OE replacement, these rotors deliver consistent, reliable stopping power with enhanced corrosion resistance right out of the box.

DFC rotors are cast from premium G3000/G11H18 hi-carbon iron, a formulation that incorporates Molybdenum, Chromium, and Carbon to enhance noise-dampening characteristics while providing superior strength, thermal conductivity, and long-term durability compared to standard iron discs.

Key Features:

• GEOMET® Coating: A genuine GEOMET® finish is applied across the entire rotor surface, delivering superior corrosion protection without the need for additional preparation — processed dry, shipped dry, and ready to install
• Hi-Carbon Alloy Construction: Premium G3000/G11H18 iron casting provides high strength, noise dampening, and increased thermal conductivity
• 100% Precision Mill-Balanced: Ensures smooth, vibration-free stopping at any speed
• OE Vane Configuration: Matches original equipment vane design for proper and maximum heat dissipation
• Disc Thickness Variation (DTV): .010mm maximum for consistent pedal feel
• Lateral Runout: .050mm maximum for smooth, stable braking
• Fine-Turned Finish (1.6 RMS): Improves initial rotor and pad break-in performance
• Electronic Inspection Certified: Each rotor passes a 100% electronic inspection measuring over 20 attributes to confirm OE compliance
• Plain (Blank) Design: Smooth rotor face ideal for street and everyday driving applications

The GEOMET® coating is simply and safely swept away by the friction material during initial bedding, leaving no harmful effects on pads or braking performance. These rotors are also compatible with DFC's application-specific brake pads for an optimized brake system upgrade. Backed by a 1-year manufacturer warranty.
