Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted by Dynamite Friction is designed to meet the braking demands of BMW 5 Series vehicles. Featuring a vented rotor construction, it allows for efficient heat dissipation during heavy braking, reducing the risk of brake fade. The rotor surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water from the braking surface, improving pad bite and overall stopping power.

The rotor's plain disc finish is complemented by a Geospec silver grey hat finish, providing corrosion resistance and a clean appearance. Additionally, the rotor is coated with a rust-resistant layer to protect against environmental wear. With a nominal thickness of 20 mm and a discard thickness of 18.4 mm, this rotor maintains structural integrity and performance throughout its service life.
