Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots for improved brake pad bite and heat management. The black zinc coating on the rotor hat provides corrosion resistance, extending rotor life in various driving environments. This product line is tailored for drivers seeking rotors that maintain performance and durability on vehicles such as the Audi 4000 and Volkswagen Rabbit Convertible.

Technical Specifications and Features

This rotor features a 239 mm outside diameter and an overall height of 38.6 mm, with a center hole diameter of 65 mm. The vented design allows air to flow between rotor surfaces, reducing heat buildup during braking. The drilled and slotted surface helps evacuate gases, dust, and water, improving braking response and reducing brake fade. The rotor includes 4 bolt holes with a 100 mm bolt circle diameter and stud/lug hole diameter of 13.75 mm, ensuring proper fitment on compatible Audi and Volkswagen models.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat during aggressive driving or towing
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner braking components
• Restores braking performance on vehicles with worn or warped rotors
• Provides corrosion resistance to extend rotor service life

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18 mm before installation. The directional drilled and slotted surface requires correct orientation during mounting to maintain optimal performance. Verify compatibility with your specific Audi or Volkswagen model, including bolt pattern and rotor dimensions. Proper torque specifications should be followed when securing the rotor to avoid warping.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM standards for fit, form, and function. The rust resistant zinc black coating on the rotor hat helps prevent corrosion, contributing to long-term durability. While no specific warranty information is provided, the product is designed for consistent performance on compatible Audi and Volkswagen vehicles.
