Dynamic Friction 4004-02028 GeoSpec Coated Drilled Disc Brake Rotor Set

The Dynamic Friction 4004-02028 is a front and rear disc brake rotor set featuring DFC's proprietary GeoSpec® corrosion-resistant coating and a cross-drilled design for enhanced performance. Engineered to meet or exceed OEM specifications, these rotors deliver reliable, quiet, and vibration-free stopping power straight out of the box.

GeoSpec® Coating Technology:

• Developed to form a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings
• Processed dry, shipped dry, and ready to install — no pre-cleaning required, saving time and money during installation
• Coating is safely swept away by the friction material during break-in with no harmful effects

Precision Engineering:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and long-term durability
• CNC-machined to the tightest tolerances available for consistent performance
• OE vane configuration ensures proper and maximum heat dissipation
• 100% mill-balanced for smooth stopping and zero vibration at any speed
• Non-directional finish promotes faster break-in and smoother stops from day one

Cross-Drilled Design:

• Drilled holes reduce heat buildup during aggressive braking
• Improved wet-weather braking performance through better water evacuation
• Designed to match OEM form, fit, and function for a straightforward direct replacement

The Dynamic Friction 4004-02028 GeoSpec Coated Drilled Rotor Set is an ideal upgrade for drivers who want OE-quality reliability combined with enhanced corrosion protection and performance-oriented drilled rotor styling.
