Dynamic Friction 4522-31010 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-31010 is a GeoSpec® Coated plain disc brake rotor engineered as a direct OE replacement for reliable, long-lasting stopping power. Featuring DFC's proprietary GeoSpec® coating, these rotors deliver superior corrosion resistance over conventional paint or zinc coatings, forming a durable, attractive silver-gray finish that protects the rotor before and after installation.

• Fully coated inside and out for complete protection from the elements
• Coating is safely swept away by brake pads during bed-in with no harmful effects on braking performance
• Processed dry and shipped dry — ready to install with no pre-degreasing required

Precision Engineering:

• Engineered with premium G3000/G11H18 cast iron for strength, stability, and long-term durability
• OE vane configuration ensures proper and maximum heat dissipation
• CNC-machined to the tightest tolerances available
• Non-directional surface finish promotes faster, more even brake pad bed-in for quieter, smoother stops
• 100% precision mill-balanced to eliminate vibration at any speed
• Designed to meet OEM form, fit, and function specifications — no modifications required
• Each rotor passes a 100% electronic inspection station measuring over 20 critical attributes
