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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps to reduce brake fade by improving heat dissipation and removing gas and debris from the pad surface. The black zinc coating on the rotor hat adds a layer of rust resistance, maintaining the rotor’s structural integrity and appearance over time. This product line is tailored for drivers seeking reliable braking performance with enhanced durability.

Technical Specifications and Features

This rotor is a solid type with a nominal thickness of 10 mm and a discard thickness of 8.4 mm, ensuring it meets safety standards for replacement. The directional surface pattern is optimized for the BMW Z3’s braking system, featuring 5 bolt holes with a diameter of 14.6 mm and a bolt circle diameter of 120 mm. The rotor’s overall diameter is 272 mm, with a height of 83.2 mm and a center hole diameter of 75 mm. The plain disc finish combined with the zinc black hat finish provides a balance of performance and corrosion resistance.

Applications and Problem Solving

• Replacement rotor for worn or warped BMW Z3 brake rotors
• Improves heat dissipation to reduce brake fade during spirited driving
• Helps maintain consistent braking performance under heavy use
• Addresses rotor surface corrosion with rust resistant coating
• Enhances brake pad cleaning and gas evacuation with drilled and slotted design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 8.4 mm before installation. The directional surface requires correct orientation during mounting to maintain optimal braking performance. Verify bolt hole alignment with the 5-lug, 120 mm bolt circle pattern specific to the BMW Z3. Clean the rotor surface of any protective coatings or oils before installing brake pads. Proper torque specifications should be followed for all lug nuts.
