Dynamic Friction 4522-02013 GeoSpec Coated Drilled Disc Brake Rotor

The Dynamic Friction Company (DFC) 4522-02013 is a GeoSpec fully coated, cross-drilled disc brake rotor engineered to deliver improved stopping performance and long-lasting corrosion resistance. Designed as a direct OE replacement, this rotor is built to the same form, fit, and function as your factory brake rotor — with meaningful performance upgrades.

The GeoSpec coating is a patented, high-quality rust-prevention finish applied to the entire rotor — inside and out — forming a durable silver-gray surface that outperforms standard zinc plating and conventional paint coatings. Unlike oil-coated rotors, GeoSpec rotors are processed dry, shipped dry, and ready to install with no cleaning or preparation required.

Cross-drilled holes improve thermal management by venting heat away from the rotor surface during heavy braking. Each drilled hole is chamfered to reduce stress concentrations and minimize the potential for cracking under repeated thermal cycling. The non-directional surface finish promotes a faster, more even brake pad bed-in and contributes to quieter, smoother stops right from the first application.

Key Features:

• Full GeoSpec coating applied inside and out for superior corrosion protection over zinc and conventional paint
• Cross-drilled holes reduce rotor heat buildup during braking
• Chamfered drill holes reduce stress and minimize cracking potential
• Non-directional rotor finish promotes faster brake pad bed-in and smoother stops
• Engineered with premium G3000 cast iron for strength, durability, and OE-matching performance
• CNC-machined to tight tolerances for consistent fitment and even braking
• 100% precision mill-balanced for vibration-free stops at any speed
• Ships dry and ready to install — no cleaning or degreasing required
• GeoSpec coating is safely swept away by friction material during bed-in with no harmful effects
• OE vane configuration for proper and maximum heat dissipation

The DFC GeoSpec Coated Drilled Brake Rotor is an excellent choice for drivers seeking an OE-quality replacement with enhanced heat management and corrosion resistance. Sold individually.
