Detailed Product Features and Specifications

This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering enhanced braking efficiency through advanced rotor surface design. The drilled and slotted surface helps to evacuate gases, dust, and water, improving pad contact and braking consistency. The vented rotor design aids in heat dissipation, reducing the risk of brake fade during demanding driving conditions.

The rotor features a directional surface type, which means it is designed to rotate in a specific direction to maximize performance. The hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance, while the disc itself has a plain finish. Additionally, the rotor is coated with a rust-resistant layer to protect against corrosion and extend service life.

Applications and Problem Solving

• Improves braking performance on BMW 535i, 545i, 550i, 645Ci, and 650i models
• Reduces brake fade during high-temperature conditions
• Minimizes brake dust buildup for cleaner wheels
• Enhances heat dissipation to prevent rotor warping
• Provides consistent braking response under wet or dry conditions

Installation Notes and Tips

When installing the Dynamite Friction 830-31063R rotor, ensure the rotor is mounted with the directional surface facing the correct rotation direction as indicated on the rotor. Verify that the bolt hole pattern matches the vehicle’s hub (5 bolt holes, 14.6 mm diameter, 120 mm bolt circle diameter). Check rotor thickness before installation; replace if below the discard thickness of 28.4 mm. Proper torque specifications should be followed to avoid rotor damage or uneven wear.
