Dynamic Friction 4622-17984 GeoSpec Coated Cross-Drilled Brake Rotor

The Dynamic Friction Company (DFC) 4622-17984 GeoSpec Coated Drilled Brake Rotor delivers enhanced stopping performance and long-lasting corrosion protection for passenger cars and light trucks. Engineered as a direct OEM replacement, this cross-drilled rotor combines premium materials, precision machining, and DFC's proprietary GeoSpec coating for a ready-to-install brake rotor upgrade.

GeoSpec Coating Technology:

DFC's patented GeoSpec coating forms a durable, attractive silver-gray finish that fights rust and corrosion far better than conventional paint or zinc coatings. Each rotor is processed dry and shipped dry — no cleaning or additional preparation required before installation. The coating is safely swept away by the brake pad friction material during normal break-in with no harmful effects.

Key Features:

• Premium G3000/G11H18 iron casting for superior strength, stability, and extended service life
• Cross-drilled holes reduce heat buildup on the rotor surface for improved fade resistance
• Chamfered drill holes reduce the potential for cracking under thermal stress
• CNC-machined to tight tolerances for precise fitment and consistent performance
• OE vane configuration ensures proper airflow and maximum heat dissipation
• 100% mill-balanced for vibration-free braking at any speed
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter stops
• Direct OEM replacement — matches original form, fit, and function

The DFC 4622-17984 is part of DFC's GeoSpec Drilled rotor lineup, designed for drivers seeking improved thermal management and corrosion protection over a standard blank replacement rotor. Sold individually.
