Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to improve brake pad bite and reduce heat buildup. The black zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of performance-oriented vehicles like the BMW Z4, offering a balance of durability and effective braking under varied driving conditions.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat generated during braking. The rotor’s surface is both drilled and slotted, enhancing water and debris evacuation while maintaining pad contact and reducing brake fade. The directional design ensures the slots and drilled holes are oriented to optimize performance when installed correctly. The rotor’s nominal thickness is 24 mm, with a discard thickness of 22.4 mm, indicating when replacement is necessary. The zinc black finish on the hat area provides rust resistance, important for longevity in various environments.

Applications and Problem Solving

• Improves braking performance for BMW Z4 models
• Reduces brake fade during aggressive or repeated braking
• Helps prevent rotor warping caused by excessive heat
• Minimizes rust and corrosion on rotor hats
• Enhances water and debris clearance for consistent braking in wet conditions

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented according to the vehicle’s rotation direction for optimal performance. Verify bolt hole alignment with the BMW Z4’s hub using the 5-bolt pattern and 120 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 24 mm. Proper torque specifications should be followed to avoid rotor damage or uneven wear.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM standards for fit and function on BMW Z4 vehicles. The rust resistant coating and vented design contribute to durability and consistent braking performance. Warranty information is available through the manufacturer and should be consulted for coverage details.
