Dynamic Friction 4522-11023 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-11023 GeoSpec Coated Plain Brake Rotor delivers premium OE-replacement braking performance backed by DFC's industry-leading corrosion protection technology. Designed as a direct, no-modification-required replacement, this rotor meets the same form, fit, and function as your original equipment brake rotor.

GeoSpec® Coating Technology:

Unlike conventional paint or zinc coatings, DFC's patented GeoSpec® coating forms a durable, attractive silver-gray finish that provides superior rust and corrosion resistance. All GeoSpec rotors are completely coated inside and out, protecting the rotor both before and after installation. The coating is designed to safely sweep away during normal pad bed-in with no harmful effects on friction surfaces.

Key Features:

• Ready to Install — Processed dry and shipped dry; no pre-degreasing or additional preparation required, saving time and money during installation
• Premium G3000/G11H18 Iron Castings — Engineered for superior strength, stability, and long-lasting durability
• OE Vane Configuration — Original Equipment vane geometry ensures proper and maximum heat dissipation
• CNC-Machined to Tight Tolerances — Precision machining delivers consistent, repeatable braking performance
• 100% Mill-Balanced — Every vented rotor is precision cut and electronically mill-balanced for smoother stopping and zero vibration at any speed
• Non-Directional Finish — Promotes faster brake pad bed-in and quieter, smoother stops
• Superior Corrosion Protection — Outperforms conventional zinc and paint coatings for extended rotor life
• 1-Year Warranty — Coverage against defects in materials and workmanship

The DFC GeoSpec plain (smooth/blank) rotor surface is ideal for everyday driving, normal commutes, and OE-style replacement applications. Each rotor passes a 100% inspection station measuring all critical attributes before leaving the facility, ensuring consistent quality and reliable stopping power right out of the box.
