Dynamic Friction 4812-46023 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4812-46023 is a GeoSpec Coated Plain Disc Brake Rotor engineered as a direct OEM replacement. Featuring DFC's proprietary GeoSpec corrosion-resistant coating, this rotor arrives ready to install with no pre-degreasing or additional preparation required — saving time and money during the brake job.

GeoSpec Coating:

• Specially formulated patented paint forms a durable, attractive silver-gray finish
• Fights rust far better than conventional paint or zinc coatings
• Coating is safely and cleanly swept away by friction material during break-in with no harmful effects

Key Features:

• Engineered with premium G3000/G11H18 iron castings for optimal strength, stability, and durability
• Original Equipment (OE) vane configuration for proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed
• Non-directional surface finish promotes faster brake pad bed-in and quieter, smoother stops
• Designed to meet the same form, fit, and function as OEM brake rotors — no modifications required
• All vented rotors 100% inspected for balance and electronically mill-corrected if necessary
• Each rotor passes a 100% inspection station measuring all critical attributes to ensure OE specification compliance

The DFC 4812-46023 GeoSpec rotor is backed by a 1-year manufacturer's warranty against defects, and is sold individually (1 rotor per pack). It is ideal for normal commute, performance street driving, towing, and off-road applications.
