Dynamic Friction 4522-40008 GeoSpec Coated Plain Disc Brake Rotors - 2-Wheel Set

The Dynamic Friction Company (DFC) 4522-40008 GeoSpec Coated Plain Brake Rotors deliver reliable, long-lasting stopping power with superior corrosion resistance. Engineered as a direct OEM replacement, these plain (smooth) rotors are ready to install right out of the box — no degreasing or additional prep required.

GeoSpec® Coating Technology:

• Proprietary patented paint forms a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings
• Fully coated inside and out for complete corrosion protection before and after installation
• Coating is safely swept away by friction material during bed-in — no harmful effects on braking performance

Precision Engineering:

• Manufactured from premium G3000/G11H18 iron castings for superior strength, stability, and durability
• CNC-machined to the tightest market tolerances for consistent, accurate fitment
• OE vane configuration ensures proper and maximum heat dissipation
• Non-directional finish promotes faster, more even brake pad bed-in for quieter, smoother stops
• 100% precision cut and mill-balanced for vibration-free stopping at any speed

Quality Assurance:

• Each rotor passes a 100% inspection station measuring all critical attributes to confirm OE specifications are met
• All vented rotors electronically mill-balanced and corrected where necessary
• Designed to meet the same form, fit, and function as OEM brake rotors — no modifications required

The DFC GeoSpec program covers a broad range of domestic and import passenger cars and light trucks, making this one of the most comprehensive coated rotor lines available. Ideal for normal daily commuting, performance street driving, and towing applications.
