Dynamic Friction 4812-74030 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4812-74030 is a GeoSpec fully coated plain (blank) disc brake rotor engineered to deliver OEM-quality stopping performance with superior corrosion resistance. Developed to form a durable and attractive silver-gray finish, DFC GeoSpec Coated Brake Rotors fight rust far better than conventional paint or zinc coatings.

All GeoSpec rotors are completely coated — inside and out — using a high-quality rust prevention coating, making them ideal for all climates and driving conditions. Each DFC GeoSpec Coated Brake Rotor is processed dry, shipped dry, and ready to install without any additional preparation — saving a tremendous amount of time and money during installation.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and durability.
• Original Equipment (OE) vane configuration to ensure proper and maximum heat dissipation.
• Provides superior corrosion protection over zinc and conventional painting; CNC-machined to the tightest tolerances.
• 100% precision cut and mill-balanced for smoother stopping and zero vibration at any speed.
• Non-directional finish to promote faster break-in and smoother stops.
• Each rotor passes a 100% inspection station that measures all critical attributes to ensure OE specifications are met.
• GeoSpec coating is designed not to contaminate friction and rotor surfaces, ensuring proper braking bed-in and wear characteristics.

This rotor features a smooth plain surface finish and is designed to meet the same form, fit, and function as OEM brake rotors. It is a direct-fit replacement that requires no modifications for a straightforward installation.
