About 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 slots with a black zinc-coated hat finish. This design improves heat dissipation and reduces brake fade while providing corrosion resistance. The directional surface pattern is tailored to maintain consistent braking performance under demanding conditions, making it suitable for Audi models requiring reliable stopping power.

Detailed Product Description

This disc brake rotor is constructed with a vented design to allow air circulation between the rotor surfaces, which helps reduce heat buildup during braking. The drilled and slotted surface enhances water and debris evacuation, improving brake pad contact and reducing the risk of glazing. The zinc black hat finish and rust resistant coating protect the rotor from corrosion, extending its service life. With a 5-bolt hole pattern and a 112 mm bolt circle diameter, this rotor ensures a secure and precise fit on compatible Audi vehicles. The directional surface type is engineered to optimize braking efficiency and pad wear.

Applications and Problem Solving

• Reduces brake fade during high-performance or repeated braking
• Improves heat dissipation to prevent rotor warping
• Enhances wet weather braking by channeling water away
• Minimizes rust and corrosion for longer rotor life
• Provides consistent braking performance for Audi A4, A6, S4, and Allroad Quattro models

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28 mm before installation. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify the bolt hole pattern and center hole diameter match the vehicle specifications. Properly torque lug nuts to manufacturer specifications to avoid rotor damage or uneven wear. Directional rotors must be installed following the indicated rotation direction for optimal performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and zinc black hat finish provide added durability against environmental factors. While no specific warranty information is provided, these rotors are designed for reliable performance and longevity when installed and maintained according to manufacturer guidelines.
