Dynamic Friction 4804-76039 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) GeoSpec Coated Plain Disc Brake Rotor (4804-76039) is a premium OE-replacement brake rotor engineered for reliable, long-lasting stopping performance. Designed to meet the same form, fit, and function as your original equipment rotor, this blank/plain-face rotor is an ideal direct-fit replacement for everyday driving.

DFC GeoSpec rotors are completely coated inside and out using a patented corrosion-resistant paint that forms a durable, attractive silver-gray finish — offering superior rust protection compared to conventional zinc or standard paint coatings. The coating is safely swept away by the friction material during the break-in process with no harmful effects on braking performance.

Key Features:

• Full GeoSpec Coating: Fully coated inside and out with patented corrosion-resistant paint for superior rust protection over zinc or conventional coatings
• Premium G3000/G11H18 Iron Casting: Engineered for strength, stability, and long-term durability
• OE Vane Configuration: Replicates precise original equipment vane geometry for proper and maximum heat dissipation
• CNC-Machined to Tight Tolerances: Ensures consistent performance and precise fitment
• Non-Directional Surface Finish: Promotes faster, more even brake pad bed-in and quieter, smoother stops
• 100% Mill-Balanced: Precision mill-balanced for vibration-free braking at any speed
• Ready to Install: Processed dry and shipped dry — no cleaning required before installation
• Plain/Blank Face: Smooth rotor surface ideal for standard street and daily-driving applications

DFC GeoSpec rotors are part of one of the most complete coated rotor programs in the industry, covering a wide range of foreign and domestic passenger cars and light trucks. The ready-to-install design eliminates the need to clean an oil-coated rotor, saving valuable installation time. Backed by a limited warranty for added peace of mind.
