Dynamic Friction 641-63124R GeoSpec Dimpled Slotted Disc Brake Rotor - Right

The Dynamic Friction Company (DFC) 641-63124R is a GeoSpec Dimpled and Slotted disc brake rotor engineered for drivers who demand improved braking performance over a standard OE replacement rotor. Part of DFC's popular 641-series GeoSpec line, this rotor features a combination of surface dimples and precision-cut slots designed to enhance heat dissipation and pad bite.

GeoSpec Coating Technology:

• Coated with a patented silver-gray finish that provides superior rust resistance compared to conventional paint or zinc coatings
• Processed dry and shipped dry — ready to install with no additional cleaning or prep required
• Coating is safely swept away by the friction material during break-in with no harmful effects

Performance Features:

• Dimpled surface reduces heat buildup across the rotor face and helps expel brake dust and gases
• Precision slots remove brake debris, prevent pad glazing, and improve bite for shorter stopping distances — especially in wet conditions
• Non-directional surface finish promotes faster, more even brake pad bed-in for quieter, smoother stops
• Machined to tight tolerances at state-of-the-art facilities to meet or exceed OE specifications
• Each rotor passes a 100% electronic inspection measuring over 20 attributes for consistent quality

Construction:

• Premium cast iron construction for strength and long-lasting durability
• Right-side fitment (position: right)
• Sold individually — one rotor per package

The DFC 641-63124R is an excellent upgrade for daily driving, towing, or any application where improved thermal management and reliable stopping power are priorities. DFC maintains one of the largest brake part inventories in the industry, covering domestic and foreign vehicles from the 1930s to present.
