Dynamic Friction 4622-18905 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4622-18905 is a GeoSpec fully coated plain (blank) disc brake rotor engineered as a direct OEM replacement. Designed to meet or exceed original equipment specifications, this rotor delivers reliable, consistent stopping performance for passenger cars and light trucks.

GeoSpec Coating Technology:

• Fully coated inside and out using a patented rust-prevention paint that forms a durable, attractive silver-gray finish — providing superior corrosion protection over conventional zinc or paint coatings
• Processed dry and shipped dry — ready to install with no cleaning or surface prep required, saving significant time during installation
• Coating is safely swept away by friction material during the bed-in process with no harmful effects on braking performance or pad wear

Premium Construction:

• Cast from premium G3000/G11H18 iron for superior strength, stability, and long-lasting durability
• CNC-machined to the tightest tolerances available in the aftermarket
• OE vane configuration duplicated precisely for optimal heat dissipation
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter, smoother stops
• 100% electronically mill-balanced for vibration-free braking at any speed

Direct OEM Replacement:

• Designed to match the same form, fit, and function as the original equipment rotor
• No modifications required — bolt-on installation
• Sold individually (1 rotor per package)

The DFC GeoSpec 4622-18905 plain rotor is an excellent choice for everyday driving, offering OEM-quality braking performance with the added benefit of superior corrosion protection both before and after installation.
