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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors with enhanced surface features such as drilled holes and slots. These design elements help reduce brake fade by improving heat and gas dissipation during braking. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking reliable braking components compatible with specific Volkswagen models.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat buildup during braking. The directional slotted and drilled surface improves water and debris evacuation, maintaining consistent brake pad contact. The rotor has a nominal thickness of 22mm and a discard thickness of 20mm, ensuring safe replacement intervals. The zinc silver finish on the hat offers rust resistance, while the plain finish on the disc surface maintains effective braking friction. The rotor features five bolt holes with a 100mm bolt circle diameter and a center hole diameter of 65mm, matching the fitment requirements for Volkswagen Corrado, Golf, Jetta, and Passat models.

Applications and Problem Solving

• Replaces worn or warped rotors on Volkswagen Corrado, Golf, Jetta, and Passat
• Addresses brake fade caused by excessive heat during aggressive driving
• Improves braking performance in wet conditions through slotted and drilled design
• Prevents rust and corrosion on rotor hats for longer service life
• Ensures proper fitment with 5-lug bolt pattern and precise dimensions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20mm before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting. Verify the bolt hole pattern and center hole diameter match the vehicle specifications. Use proper torque settings on lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Volkswagen vehicles. The rust resistant coating and vented design contribute to durability and consistent braking performance. While no specific warranty information is provided, the product is designed for reliable service within the recommended thickness limits.
