DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This design reduces brake fade and helps maintain consistent braking performance under demanding conditions. The vented rotor construction further aids in cooling, making it suitable for both daily driving and more spirited use on compatible Volvo vehicles.

Detailed Product Description

This disc brake rotor features a 345 mm outside diameter and a nominal thickness of 30 mm, with a discard thickness of 27.5 mm to ensure safe replacement intervals. The rotor is vented to allow airflow between the braking surfaces, which helps reduce heat buildup during braking. The drilled and slotted surface design enhances pad cleaning and gas evacuation, improving braking response and reducing the risk of brake fade. The rotor’s directional surface is engineered to optimize performance in the intended rotation direction.

The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the entire rotor is coated with a rust-resistant layer to extend service life, especially in environments prone to moisture and road salt. The bolt pattern includes five holes with a 15.8 mm diameter and a bolt circle diameter of 108 mm, matching the specifications for various Volvo models.

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify that the bolt hole pattern matches the vehicle hub before installation. Clean the rotor surface with brake cleaner to remove any protective coatings or residues prior to mounting. Check the rotor thickness and discard thickness to confirm the rotor is within safe operating limits. Proper torque specifications should be followed when tightening lug nuts to avoid rotor warping.
