Dynamic Friction 4814-31056 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction Company 4814-31056 is a GeoSpec® Fully Coated Plain (Smooth) Disc Brake Rotor engineered to deliver OE-quality braking performance with superior corrosion resistance. Featuring DFC's proprietary GeoSpec® coating, this rotor is protected inside and out with a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings — and requires no cleaning or degreasing prior to installation.

Key Features:

• GeoSpec® Full Coating: Patented rust-prevention coating applied to the entire rotor — hat, vanes, and friction surfaces — for lasting corrosion protection before and after installation
• 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
• CNC-Machined to Tight Tolerances: Precision machining guarantees consistent performance and direct OE fitment with no modifications required
• Non-Directional Surface Finish: Promotes faster, more even brake pad bed-in for quieter and smoother stops
• 100% Mill-Balanced: All vented rotors are electronically mill-balanced for vibration-free braking at any speed
• Ready to Install: Processed and shipped dry — no degreasing or additional prep needed, saving time and money during installation
• 100% Inspected: Each rotor passes a full inspection station verifying all critical attributes meet OE specifications
