Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and aid in heat and gas dissipation. The black zinc coating on the rotor hat provides corrosion resistance, making it suitable for vehicles exposed to varying weather conditions. This product line is tailored for drivers seeking rotors that maintain consistent braking under moderate to demanding conditions.

Technical Description and Specifications

This disc brake rotor features a vented design that allows air to flow between the rotor faces, reducing heat buildup during braking. The drilled and slotted surface helps evacuate brake dust, water, and gases, which can improve braking response and reduce fade. The rotor’s nominal thickness is 25 mm, with a discard thickness of 22 mm, ensuring a clear service limit for safety. The zinc black finish on the hat section offers rust resistance, extending the rotor’s service life. With a 5-lug bolt pattern and 100 mm bolt circle diameter, this rotor fits specific Audi and Volkswagen models including the A1, Beetle, Golf, Jetta, and Polo. The directional surface design requires correct installation orientation to maximize performance.

Compatible Vehicles and Common Applications

• Replacement rotor for Audi A1 brake system maintenance
• Upgrading Volkswagen Beetle braking components
• Brake rotor replacement for Volkswagen Golf and Jetta
• Suitable for Volkswagen Polo brake system repairs
• Addressing brake fade and rotor wear issues on compatible models

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated by the manufacturer. Verify the bolt hole alignment matches the vehicle’s hub with the 5-lug, 100 mm bolt circle pattern. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 22 mm. Clean the rotor surface to remove any protective coatings or residues before mounting. Proper torque specifications should be followed for lug nuts to avoid warping.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit and function. The rust resistant coating and zinc black hat finish contribute to long-term durability. While specific warranty details are not provided, the rotor is designed for consistent performance and safety on compatible Audi and Volkswagen vehicles when installed and maintained properly.
