Dynamic Friction 4822-31147 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4822-31147 GeoSpec Coated Plain Brake Rotor is a direct OE-replacement disc brake rotor engineered for reliable, consistent stopping performance. Featuring DFC's proprietary GeoSpec® corrosion-resistant coating, this rotor arrives ready to install straight out of the box — no cleaning or prep work required.

The GeoSpec coating forms a durable, attractive silver-gray finish that provides superior rust and corrosion protection compared to conventional paint or zinc coatings. Because the rotor is processed and shipped dry, installation time is significantly reduced. The coating is safely swept away by the brake pad friction material with no harmful effects on braking performance.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for strength, stability, and durability
• CNC-machined to the tightest tolerances for precise fitment and performance
• Original Equipment (OE) vane configuration for proper and maximum heat dissipation
• Non-directional surface finish promotes faster brake pad bed-in and smoother, quieter stops
• 100% precision cut and mill-balanced for vibration-free stopping at any speed
• 100% inspected to meet OE specifications for form, fit, and function
• GeoSpec coating ships dry — no cleaning required prior to installation
• Smooth/plain rotor surface — ideal for OE replacement and daily driving applications

The 4822-31147 is backed by Dynamic Friction Company's commitment to quality, passing a 100% inspection process to ensure every critical dimension meets or exceeds OEM standards before leaving the facility.
