Dynamic Friction 4004-21019 DFC GeoSpec Coated Disc Brake Rotor

The Dynamic Friction Company (DFC) 4004-21019 GeoSpec Coated Brake Rotor is a direct-fit OE replacement disc brake rotor engineered for reliable, consistent stopping performance. Manufactured to strict OEM dimensional tolerances, this rotor installs without modification and restores factory braking feel and response.

The GeoSpec coating is a corrosion-resistant finish applied to the non-friction surfaces of the rotor, helping to prevent rust bloom and protecting the rotor during storage and after installation. This coating also gives the rotor a clean, finished appearance without affecting braking performance on the friction surfaces.

Key Features:

• OEM-matched dimensions and specifications for a direct, no-modification fit
• GeoSpec corrosion-resistant coating on non-friction surfaces to resist rust and oxidation
• Plain (non-slotted, non-drilled) disc design for OE-equivalent street performance
• Precision machined for minimal runout and smooth, vibration-free braking
• High-quality gray iron construction for durability and consistent heat dissipation
• Each rotor is balanced and tested to meet or exceed OEM standards
• Manufactured by Dynamic Friction Company (DFC), a trusted brake components specialist

The DFC 4004-21019 is a plain-style rotor, making it an ideal choice for everyday street driving and OEM replacement applications. Paired with quality brake pads, this rotor delivers confident, fade-resistant braking performance over the life of the component.
