Dynamic Friction 4522-31056 GeoSpec Coated Plain Disc Brake Rotor Kit

The Dynamic Friction Company (DFC) 4522-31056 GeoSpec Coated Plain Brake Rotors deliver OE-quality stopping performance with superior corrosion resistance. Each rotor is fully coated inside and out with DFC's proprietary silver-gray GeoSpec finish, engineered to fight rust far more effectively than conventional paint or standard zinc coatings.

These plain (smooth) rotors are precision-manufactured from premium G3000/G11H18 cast iron and CNC-machined to the tightest tolerances in the market, ensuring a precise OE-spec fit and consistent braking feel. The original equipment vane configuration is replicated exactly to maximize heat dissipation and maintain rotor integrity under repeated braking cycles.

Every DFC GeoSpec rotor ships processed dry and ready to install — no degreasing or pre-cleaning required. The GeoSpec coating is designed to be safely swept away by the friction material during normal bed-in, with no harmful effects on pads or braking surfaces.

Key Features:

• Proprietary GeoSpec coating provides superior rust and corrosion protection over zinc or conventional paint
• Engineered with premium G3000/G11H18 iron castings for strength, stability, and long-term durability
• OE vane configuration for proper and maximum heat dissipation
• CNC-machined to the tightest tolerances for precise fit and smooth performance
• 100% mill-balanced for vibration-free stopping at any speed
• Non-directional finish promotes faster brake pad bed-in and quieter stops
• Ready to install — no pre-degreasing or additional preparation needed
• 100% inspected to meet or exceed OE specifications

The DFC GeoSpec 4522-31056 is an ideal OE replacement brake rotor kit offering professional-grade quality and lasting corrosion protection straight out of the box.
