Dynamic Friction 4524-40017 GeoSpec Coated Plain Rotor and Brake Pad Kit

The Dynamic Friction Company 4524-40017 is a GeoSpec Coated plain disc brake rotor and pad kit engineered to deliver OE-quality braking performance with superior corrosion resistance. Featuring DFC's proprietary GeoSpec® coating, these rotors form a durable, attractive silver-gray finish that fights rust far more effectively than conventional paint or zinc coatings — protecting the rotor before, during, and after installation.

Each rotor arrives processed dry, shipped dry, and ready to install — no pre-cleaning or degreasing required. The GeoSpec coating is safely swept away by the friction material during the bed-in process, with no harmful effects on pad or rotor surfaces, ensuring proper break-in from the first stop.

Key Features:

• Engineered with premium G3000/G11H18 iron castings for exceptional strength, stability, and long-term durability
• CNC-machined to the tightest tolerances available for precise fitment and consistent performance
• Original Equipment (OE) vane configuration for proper and maximum heat dissipation
• Non-directional finish promotes faster, more even brake pad bed-in and quieter, smoother stops
• 100% precision cut and mill-balanced for vibration-free stopping at any speed
• Fully coated inside and out — superior corrosion protection over zinc or conventional paint
• 100% inspected at a dedicated QC station to verify all critical OE specifications are met
• Direct OE replacement — designed to meet the same form, fit, and function as factory rotors

The DFC GeoSpec program covers over 1,400 SKUs across foreign and domestic passenger cars and light trucks, making it one of the most comprehensive coated rotor programs available. This kit pairs GeoSpec coated plain rotors with DFC brake pads for a complete, matched brake system upgrade.
