Dynamic Friction 4804-74015 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4804-74015 is a GeoSpec Coated Plain Disc Brake Rotor engineered to deliver OEM-quality braking performance with superior long-term corrosion resistance. The GeoSpec coating forms a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings — protecting the rotor fully, inside and out, before and after installation.

Each rotor arrives processed dry and ready to install — no degreasing or additional preparation required, saving time and effort during the brake job.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• GeoSpec coating provides superior corrosion resistance over zinc and conventional paint coatings
• Full inside-and-out coating protects the rotor before and after installation
• OE vane configuration ensures proper and maximum heat dissipation
• CNC-machined to the tightest market tolerances for precise fit
• 100% mill-balanced for vibration-free, smooth stopping 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 — direct OEM replacement
• 100% inspected at final quality station for all critical attributes

The DFC GeoSpec program covers over 1,400 SKUs across a wide range of foreign and domestic passenger cars and light trucks, making it one of the most complete coated rotor programs available. The GeoSpec coating is designed not to contaminate friction or rotor surfaces, ensuring a proper bed-in process and consistent, even wear over the life of the rotor.
