About the DFC GEOSPEC Coated Rotor - Dimpled Product Line

The DFC GEOSPEC Coated Rotor - Dimpled line from Dynamite Friction focuses on combining advanced surface treatments with functional design elements. The dimpled surface enhances braking efficiency by promoting better pad bite and heat dissipation, while the Geospec silver grey coating on the rotor hat provides corrosion resistance. This product line is tailored for drivers seeking consistent braking performance and rotor longevity in demanding driving conditions.

Detailed Product Description

This disc brake rotor features a directional, dimpled surface type that optimizes friction and heat dispersion during braking. The vented rotor design allows air to flow between the rotor faces, reducing the risk of overheating and brake fade. With a plain disc finish and a robust rust-resistant coating, the rotor maintains structural integrity and appearance over time. The rotor’s outside diameter measures 395 mm, and it has a discard thickness of 34.4 mm, ensuring it meets safety standards for replacement. The Geospec silver grey finish on the rotor hat adds an extra layer of protection against corrosion, making it suitable for various driving environments.
