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

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and precision slots to optimize brake pad contact and gas evacuation. The black zinc coating on the rotor hat enhances rust resistance, extending rotor life in various driving environments. This product line is designed to meet the specific braking demands of performance-oriented vehicles like the BMW Z4, providing a balance of durability and heat management.

Technical Specifications and Features

This disc brake rotor is vented to allow air flow between the rotor surfaces, which helps dissipate heat generated during braking. The directional slotted and drilled surface improves water and debris removal from the rotor face, reducing brake fade and maintaining consistent braking performance. The rotor’s nominal thickness is 19 mm, with a discard thickness of 17.4 mm, ensuring safe replacement intervals. The rotor features five bolt holes with a diameter of 14.2 mm and a bolt circle diameter of 120 mm, matching the BMW Z4’s hub specifications. The hat finish is zinc black, providing a rust-resistant coating to protect against corrosion.

Applications and Problem Solving

• Replacement rotor for worn or warped BMW Z4 brake rotors
• Improves heat dissipation to reduce brake fade during spirited driving
• Enhances braking performance in wet conditions by channeling water away
• Addresses rotor corrosion issues with rust-resistant coating
• Maintains consistent braking feel with vented and directional design

Installation Notes and Tips

Ensure the rotor surface is clean and free of contaminants before installation. Verify the bolt hole pattern and diameter match the BMW Z4 specifications. Use proper torque settings on lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance. Check rotor thickness regularly and replace when below the discard thickness of 17.4 mm.

Quality Assurance

Dynamite Friction manufactures the 633-31061R rotor to meet OEM standards for fit and function. The rust-resistant zinc black coating on the rotor hat helps extend service life. While no specific warranty information is provided, this rotor is designed to provide reliable braking performance when installed and maintained according to manufacturer guidelines.
