Dynamic Friction 4004-20018 GeoSpec Coated Slotted Disc Brake Rotor

The Dynamic Friction Company (DFC) 4004-20018 GeoSpec Coated Slotted Brake Rotor is a premium OE-replacement rotor engineered for drivers who demand superior corrosion resistance and enhanced stopping performance. Featuring DFC's patented GeoSpec coating technology, this slotted rotor delivers a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings.

Key Features:

• GeoSpec Patented Coating – Forms a durable, corrosion-resistant silver-gray finish that outperforms conventional paint and zinc coatings for long-lasting protection
• Slotted Design – Precision-cut slots help evacuate heat, gases, and brake dust from the rotor surface for improved bite and consistent braking performance
• Premium G3000/G11H18 Iron Casting – Engineered for maximum strength, stability, and durability under demanding braking conditions
• CNC-Machined to Tight Tolerances – Ensures precise fit and consistent performance as an OE-style direct replacement
• OE Vane Configuration – Maintains original equipment vane geometry for proper and maximum heat dissipation
• 100% Precision Mill-Balanced – Eliminates vibration and ensures smoother stops at any speed
• Non-Directional Surface Finish – Promotes faster pad break-in and smoother stops right from installation
• Ready to Install – Processed and shipped dry with no additional pre-degreasing preparation required, saving time and labor during installation

Designed to meet the same form, fit, and function as OEM brake rotors, the DFC GeoSpec Coated Slotted Rotor is the ideal upgrade for drivers seeking improved durability and performance over a standard replacement rotor. The GeoSpec coating is safely swept away by the friction material during break-in with no harmful effects to pads or rotor surface.
