Dynamic Friction 4004-63110 GeoSpec Coated Drilled Disc Brake Rotor

The Dynamic Friction Company 4004-63110 GeoSpec Coated Drilled Brake Rotor is a direct OE-replacement disc brake rotor engineered for drivers who demand superior corrosion resistance and reliable stopping performance. Cross-drilled holes promote cooling and help sweep away brake dust and gases from the rotor surface, making this an ideal upgrade over standard blank rotors.

GeoSpec Coating Advantage:

DFC's proprietary GeoSpec coating forms a durable, attractive silver-gray finish that fights rust and corrosion far better than conventional paint or zinc coatings. The rotor ships dry and is ready to install right out of the box — no cleaning or prep work required. The coating is safely and cleanly swept away by the brake pads during the normal break-in process with no harmful effects.

Key Features:

• Premium G3000/G11H18 iron casting for superior strength, stability, and long-term durability
• Cross-drilled holes for improved heat dissipation, gas evacuation, and consistent bite
• CNC-machined to the tightest tolerances available for precise fitment and smooth operation
• OE vane configuration ensures proper and maximum heat dissipation
• 100% precision cut and mill-balanced for vibration-free stopping at any speed
• Non-directional rotor finish promotes faster break-in and smoother, quieter stops
• GeoSpec silver-gray coating provides superior corrosion protection over zinc or conventional paint
• Ships dry and ready to install — no additional preparation needed
• Designed to meet the same form, fit, and function as OEM brake rotors
• Backed by a 12,000-mile / 12-month limited warranty
