DFC GEOSPEC Coated Rotor Product Line Details

The DFC GEOSPEC Coated Rotor line by Dynamite Friction focuses on rotors with a protective coating to resist corrosion and extend service life. This coating helps maintain rotor integrity under various driving conditions, making it suitable for the Volvo XC90's braking system. The vented design enhances heat dissipation, reducing the risk of brake fade during extended use.

Technical Description and Specifications

This disc brake rotor features a nominal thickness of 30 mm and a discard thickness of 27 mm, ensuring it meets safety standards for replacement intervals. The rotor's outside diameter measures 328 mm, with an inside diameter of 68 mm, and it includes five bolt holes each with a diameter of 16.7 mm. The rotor height is 51.5 mm, designed to fit precisely on Volvo XC90 models. The vented rotor type improves airflow to dissipate heat generated during braking, which helps maintain consistent braking performance.

Applications and Problem Solving
