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 provide enhanced heat dissipation and improved braking response. The drilled and slotted surface design helps reduce brake fade by allowing gases and debris to escape, while the vented rotor construction promotes airflow to maintain optimal operating temperatures. The zinc black finish on the rotor hat adds corrosion resistance, extending the rotor's service life under various driving conditions.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 30 mm and a discard thickness of 28.4 mm, ensuring reliable performance throughout its service life. The rotor's outside diameter measures 332 mm, with an overall height of 62.3 mm. It includes five bolt holes and stud/lug holes, each with a diameter of 16.4 mm, arranged on a 120 mm bolt circle diameter. The center hole diameter is 75 mm. The rotor surface is directional, combining drilled holes and slots to optimize braking efficiency and reduce heat buildup. The vented design further aids in heat dissipation, making it suitable for demanding driving conditions.

Applications and Problem Solving

• Replacement rotor for BMW X5 and X6 models requiring vented, drilled, and slotted rotors
• Addresses brake fade caused by excessive heat during heavy braking
• Helps reduce brake dust and debris accumulation on the rotor surface
• Improves wet weather braking performance by channeling water away
• Prevents premature rotor corrosion with rust-resistant coating

Installation Notes and Tips

Ensure the rotor is installed on compatible BMW X5 or X6 models matching the specified bolt pattern and dimensions. Verify the rotor thickness before installation; replace if below the discard thickness of 28.4 mm. Properly torque all lug nuts to manufacturer specifications to maintain rotor alignment and performance. It is recommended to inspect brake pads and other braking components during rotor replacement to ensure optimal system function.

Quality Assurance

Dynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Black to meet industry standards for durability and performance. The rust-resistant zinc black coating on the rotor hat enhances corrosion protection. While no specific warranty information is provided, this rotor is designed to maintain consistent braking performance for BMW X5 and X6 vehicles when installed and maintained according to manufacturer guidelines.
