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 precision slots on a directional surface. This design aids in reducing brake fade by improving heat dissipation and gas evacuation during braking. The zinc black finish on the rotor hat provides corrosion resistance, complementing the rust-resistant coating on the rotor surface. This product line is tailored for drivers seeking reliable braking components compatible with specific BMW models.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor faces to reduce heat buildup during braking. The rotor’s nominal thickness is 23.8 mm, with a discard thickness of 22.4 mm, ensuring safe replacement intervals. The rotor measures 370 mm in outside diameter and 69 mm in overall height, fitting precisely on the specified BMW models. The bolt pattern includes five holes with a 120 mm bolt circle diameter and 16.6 mm bolt hole diameter, matching the factory specifications for secure mounting.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on BMW 550i GT and 750Li models
• Improves heat dissipation to reduce brake fade during aggressive driving or towing
• Helps maintain consistent braking performance under wet conditions due to slotted and drilled surface
• Prevents rust and corrosion with zinc black hat finish and rust-resistant coating
• Restores braking efficiency for vehicles experiencing vibration or noise from damaged rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22.4 mm before installation. Clean the rotor surface to remove any protective coating residue before mounting. Verify bolt hole alignment with the 5-lug, 120 mm bolt circle pattern on your BMW model. Use proper torque specifications to secure the rotor and avoid uneven wear or vibration. It is recommended to replace brake pads simultaneously for optimal braking performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 633-31095R rotor to meet OEM standards for fit and function on compatible BMW vehicles. The rust-resistant coating and zinc black hat finish contribute to long-term durability. Warranty information is available through the manufacturer and should be consulted for coverage details.
