Dynamic Friction 4002-63157 GeoSpec Coated Drilled Disc Brake Rotor 2-Wheel Set

The Dynamic Friction Company 4002-63157 GeoSpec Coated Drilled Brake Rotor Set delivers a performance-oriented braking upgrade backed by DFC's industry-leading corrosion protection technology. This 2-wheel set features cross-drilled rotors finished with DFC's proprietary GeoSpec® coating, a patented paint process that forms a durable, attractive silver-gray finish proven to fight rust far better than conventional paint or zinc coatings.

Each rotor ships dry and is ready to install straight out of the box — no degreasing or surface prep required. The GeoSpec coating is safely swept away by the friction material during initial bedding with no harmful effects to pads or braking performance.

Key Features:

• GeoSpec® Corrosion Protection: Patented silver-gray coating provides superior rust resistance over conventional paint or zinc coatings
• Cross-Drilled Surface: Drilled holes reduce heat buildup on the rotor face; chamfered edges minimize the risk of cracking
• Premium G3000/G11H18 Cast Iron: Engineered for strength, stability, and long-term durability under demanding braking conditions
• CNC-Machined to Tight Tolerances: Precision manufacturing ensures proper fit and consistent performance
• OE Vane Configuration: Matches original equipment vane geometry for proper and maximum heat dissipation
• 100% Precision Mill-Balanced: Eliminates vibration and brake pedal pulsation at any speed
• Non-Directional Finish: Promotes faster, more even brake pad bed-in for quieter and smoother stops
• Ready to Install: Processed dry and shipped dry — no additional preparation needed
• 100% Electronically Inspected: Each rotor passes an inspection station measuring over 20 critical attributes to confirm OE specification compliance

Designed to meet the same form, fit, and function as OEM brake rotors, the DFC 4002-63157 set is suitable for normal commuting, performance street driving, towing, and off-road use. This kit includes two individually matched GeoSpec Coated drilled rotors for a complete axle installation.
