Dynamic Friction 4522-75013 GeoSpec Coated Slotted Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-75013 is a GeoSpec Coated Slotted Disc Brake Rotor engineered to deliver superior corrosion resistance, consistent stopping performance, and a direct OEM-quality fit. Slotted rotor geometry enhances brake pad grip and helps sweep away heat, gas, and debris from the rotor surface for more confident braking under demanding conditions.

GeoSpec Coating Technology:

DFC's proprietary GeoSpec coating forms a durable silver-gray finish that fights rust and corrosion far better than conventional paint or zinc coatings. Each rotor is processed dry, shipped dry, and is ready to install straight out of the box — no cleaning or degreasing required. The coating is safely and gradually swept away by the friction material during normal break-in with no harmful effects.

Key Features:

• Premium G3000/G11H18 iron casting for outstanding strength, stability, and long-term durability
• Slotted rotor design enhances pad bite, reduces stopping distance, and expels heat and gases from the braking surface
• CNC-machined to tight tolerances for precise fitment and consistent performance
• OE vane configuration maintains proper airflow and maximum heat dissipation
• 100% precision cut and mill-balanced for vibration-free stopping at all speeds
• Non-directional surface finish promotes faster, more even brake pad bed-in and quieter stops
• Superior corrosion protection over conventional zinc or paint coatings
• Direct OEM replacement — no modifications required for installation

The DFC 4522-75013 GeoSpec Coated Slotted Rotor is the ideal upgrade for drivers seeking enhanced braking performance and long-lasting corrosion protection without sacrificing OE-level fit and function.
