Dynamic Friction 4522-31022 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-31022 is a GeoSpec Coated plain/blank disc brake rotor engineered as a direct OEM replacement. Featuring DFC's proprietary GeoSpec corrosion-resistant coating, this rotor delivers a durable, attractive silver-gray finish that outperforms conventional paint and zinc coatings in rust prevention — both before and after installation.

Key Features:

• GeoSpec Full Coating: Completely coated inside and out with a patented rust-prevention finish that fights corrosion far better than zinc or conventional paint coatings
• Premium G3000/G11H18 Iron Casting: Engineered with high-grade iron castings for superior strength, stability, and long-term durability
• OE Vane Configuration: Original Equipment vane geometry ensures proper and maximum heat dissipation under all driving conditions
• CNC-Machined to Tight Tolerances: Precision machining guarantees consistent fitment and optimal contact with brake pads
• 100% Mill-Balanced: Each vented rotor is electronically mill-balanced for smooth, vibration-free stopping at any speed
• Non-Directional Finish: Promotes faster, more even brake pad bed-in for quieter stops right from installation
• Ready to Install: Processed and shipped dry — no pre-cleaning or degreasing required, saving time during installation
• 100% Inspected: Every rotor passes a final inspection station verifying all critical attributes meet OE specifications

The DFC GeoSpec coated rotor line covers over 1,400 SKUs for foreign and domestic passenger cars and light trucks, making it one of the most comprehensive coated rotor programs available. The 4522-31022 is backed by a 1-year manufacturer warranty and is designed to meet the same form, fit, and function as the original equipment rotor it replaces.
