Dynamic Friction 4522-31018 GeoSpec Coated Plain Disc Brake Rotor

The Dynamic Friction 4522-31018 GeoSpec Coated Plain Disc Brake Rotor is a premium OE-replacement brake rotor engineered for reliable, quiet, and vibration-free stops. Coated with DFC's patented GeoSpec silver-gray finish, this rotor delivers superior rust and corrosion resistance compared to conventional paint or zinc-coated rotors — and arrives ready to install with zero prep work required.

The GeoSpec coating is processed dry and shipped dry, so there's no need to degrease or clean the rotor before installation. The coating is safely and cleanly swept away by the friction material during normal brake bed-in, with no harmful effects on brake performance.

Key Features:

• Patented GeoSpec Coating: Forms a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings
• Premium G3000/G11H18 Iron Casting: Engineered for exceptional strength, stability, and long-term durability

• 100% Precision Mill-Balanced: Delivers smoother stopping and zero vibration at any speed
• Non-Directional Surface Finish: Promotes faster, more even brake pad bed-in for quieter and smoother stops
• Ready to Install: No degreasing or pre-cleaning required — saves time and money during installation
