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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to improve brake pad bite and reduce heat buildup. The zinc silver hat finish provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of BMW vehicles requiring reliable stopping power and consistent performance under varied driving conditions.

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 a clear service life indicator. The 284 mm outside diameter and 61.1 mm overall height are engineered to fit specific BMW models precisely. The rotor features a directional surface pattern with drilled holes and slots to aid in heat dissipation and debris removal, which helps maintain braking efficiency. The zinc silver hat finish and rust resistant coating protect against corrosion, making it suitable for long-term use.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on BMW 5 and 6 Series models
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust resistant coating
• Restores proper braking surface for enhanced safety and control

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 8.4 mm before installation. Clean the hub surface and mounting points to prevent uneven rotor seating. Use the correct torque specifications for the 5 bolt holes (15 mm diameter, 120 mm bolt circle diameter) to avoid rotor warping. This rotor is directional; install with the correct orientation to maintain optimal braking performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM standards for fit and function. The rust resistant coating and zinc silver hat finish contribute to durability and corrosion resistance. While no specific warranty information is provided, this rotor is designed for reliable performance on compatible BMW models when installed and maintained properly.
