Dynamic Friction 4002-31105 GeoSpec Coated Dimpled Brake Rotors

The Dynamic Friction Company (DFC) 4002-31105 GeoSpec Coated Dimpled Brake Rotors deliver premium corrosion protection and enhanced braking performance in one ready-to-install package. Engineered with a patented silver-gray GeoSpec® coating, these rotors resist rust far more effectively than conventional paint or zinc coatings, keeping your brake system looking and performing like new.

The dimpled rotor design promotes improved heat dissipation and increased pad bite, reducing brake fade during demanding driving conditions. Each rotor is cast from premium G3000/G11H18 iron and CNC-machined to the tightest tolerances for a precise OE-equivalent fit. A non-directional surface finish accelerates pad break-in and delivers smooth, consistent stopping power from the very first stop.

Key Features:

• Patented GeoSpec® corrosion-resistant silver-gray coating — superior to zinc and conventional paint
• Dimpled rotor design for enhanced ventilation, improved pad bite, and reduced brake fade
• Premium G3000/G11H18 iron casting for superior strength, stability, and durability
• CNC-machined to tight tolerances for precise fit and quiet operation
• 100% mill-balanced for vibration-free stops at any speed
• Non-directional finish promotes faster break-in and smoother stops
• Processed dry, shipped dry — no pre-degreasing or cleaning required before installation
• Designed to match OEM vane configuration for proper heat dissipation
• No modifications required for installation

DFC GeoSpec Coated Rotors are built for everyday commuters, performance street driving, towing, and light off-road use. Sold as a 2-wheel set, these rotors are a direct OE replacement that save time and money during installation by eliminating the need for pre-cleaning.
