Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is designed to provide reliable braking performance with enhanced heat dissipation and reduced brake fade. The drilled and slotted surface improves water and debris evacuation, while the vented rotor design helps maintain optimal operating temperatures. The zinc silver coating on the rotor hat offers corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This disc brake rotor has a nominal thickness of 23.8 mm and a discard thickness of 22.4 mm, ensuring precise wear limits for safety and performance. The rotor's outside diameter measures 345 mm with an overall height of 74 mm, fitting the specified BMW models accurately. The rotor features a directional surface type with both drilled holes and slots, which aid in heat dissipation and brake pad cleaning. The rotor is vented to allow airflow between the braking surfaces, reducing heat buildup during heavy braking. The zinc silver hat finish provides rust resistance, while the plain disc finish maintains a clean appearance.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on BMW 750i, 750Li, 760i, and 760Li
• Improves braking performance by reducing heat and brake fade
• Helps prevent rust and corrosion with zinc silver coating
• Enhances water and debris evacuation with drilled and slotted design
• Maintains braking consistency under demanding driving conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22.4 mm before installation. The rotor features 5 bolt holes with a 16.7 mm diameter and a 120 mm bolt circle diameter, matching the OEM specifications for the compatible BMW models. Properly torque all lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.
