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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction offers rotors designed with both drilled holes and slots to improve braking efficiency and reduce heat buildup. The black zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for Volkswagen models requiring precise fitment and reliable vented rotors to maintain consistent braking performance under various driving conditions.

Technical Description and Specifications

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The directional slotted and drilled surface helps channel away brake dust, water, and gases, which can improve pad contact and reduce brake fade. The rotor's nominal thickness is 20 mm, with a discard thickness of 18 mm, indicating when replacement is necessary. The zinc black finish on the rotor hat offers rust resistance, while the plain finish on the disc surface ensures compatibility with a wide range of brake pads. The rotor features four bolt holes arranged on a 100 mm bolt circle diameter, matching the stud/lug hole pattern for Volkswagen Cabrio, Derby, Golf, Jetta, Passat, and Quantum models.

Compatible Applications and Problem Solving

• Replacement for worn or warped rotors on Volkswagen Cabrio, Derby, Golf, Jetta, Passat, and Quantum
• Addresses brake fade caused by excessive heat buildup during heavy braking
• Improves braking performance in wet conditions by channeling water away from the rotor surface
• Reduces brake dust accumulation for cleaner braking components
• Prevents rust and corrosion on the rotor hat for longer service life

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify the bolt hole pattern and center hole diameter match your vehicle specifications. Properly torque all lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Volkswagen vehicles. The rust-resistant zinc black finish on the rotor hat helps maintain durability over time. While specific warranty details are not provided, Dynamite Friction products are generally backed by quality control standards to ensure reliable performance and fitment.
