Dynamic Friction 4522-31016 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4522-31016 is a GeoSpec® Coated Plain (Smooth) Disc Brake Rotor engineered to deliver OE-equivalent braking performance with superior corrosion protection. GeoSpec® coating forms a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings — and is processed dry, shipped dry, and ready to install with no additional prep or degreasing required.

Key Features:

• GeoSpec® Fully Coated Finish — Patented coating covers the entire rotor (inside and out), providing superior corrosion protection over zinc and conventional paint coatings
• Premium G3000/G11H18 Iron Casting — Engineered for exceptional strength, stability, and long-term durability
• OE Vane Configuration — Duplicates original equipment vane design for proper and maximum heat dissipation
• CNC-Machined to Tight Tolerances — Ensures precise fitment and consistent performance
• 100% Mill-Balanced — Precision cut and electronically mill-balanced for smoother stopping and zero vibration at any speed
• Non-Directional Finish — Promotes faster, more even brake pad bed-in and quieter, smoother stops
• Ready to Install — No pre-degreasing or cleaning required; saves time and money during installation
• 100% Inspected — Every rotor passes a full inspection station measuring all critical attributes to meet OE specifications
• Plain / Smooth Rotor Style — Ideal for normal commuting, daily driving, and OE replacement applications

The GeoSpec® coating is safely swept away by the brake pad friction material during the bed-in process with no harmful effects, ensuring proper break-in and long-term wear characteristics. Sold as a single rotor.
