Dynamic Friction 4824-31048 GeoSpec Coated Drilled Disc Brake Rotor

The Dynamic Friction Company (DFC) 4824-31048 is a GeoSpec Coated Drilled disc brake rotor engineered as a direct OE replacement. Featuring DFC's proprietary GeoSpec patented coating, this rotor is fully coated inside and out with a durable silver-gray rust-prevention finish that outperforms conventional zinc or painted coatings — and requires zero pre-installation cleaning or degreasing.

The drilled hole pattern improves initial brake pad bite, aids in heat dissipation during repeated braking, and helps evacuate brake dust and gases from the rotor surface. Each rotor is cast from premium G3000 iron and CNC-machined to the tightest tolerances to duplicate OE vane configurations and fitment precisely.

Key Features:

• GeoSpec fully coated — patented silver-gray coating on all surfaces for superior corrosion protection over zinc or conventional paint
• Drilled design — improves pad bite, manages heat buildup, and clears brake dust and gases
• Premium G3000 iron casting — duplicates OE vane configuration for proper heat dissipation and structural integrity
• CNC-machined to tight tolerances — ensures precise OE-style form, fit, and function
• Non-directional brake surface finish — promotes faster, more even brake pad bed-in and quieter, smoother stops
• 100% electronically inspected — each rotor passes a multi-attribute inspection station covering over 20 dimensional checks
• Ready to install — processed dry and shipped dry; no pre-cleaning or degreasing required
• Vented rotor construction for maximum heat dissipation
• 5-lug bolt pattern, 325 mm outside diameter

The GeoSpec coating is designed not to contaminate friction surfaces, ensuring a proper brake bed-in and consistent long-term wear characteristics. The coating is simply and safely swept away by the friction material during normal operation with no harmful effects.
