About the DFC Brake Rotor - Drilled and Slotted - Black Product Line

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 heat dissipation. The black zinc coating on the rotor hat provides corrosion resistance, extending rotor life in demanding environments. This product line is designed to meet the braking needs of performance-oriented and daily-driven vehicles alike.

Detailed Product Description

This solid disc brake rotor features a directional surface with both drilled holes and slots, which help to evacuate gases, dust, and water from the braking surface. The nominal thickness of 9 mm ensures durability, while the discard thickness of 7 mm indicates when replacement is necessary to maintain safe braking. The rotor’s zinc black hat finish offers rust resistance, protecting the mounting area from corrosion. With 5 bolt holes arranged on a 100 mm bolt circle diameter, this rotor fits securely on compatible Audi and Volkswagen vehicles. The 232 mm outside diameter and 39.5 mm height are engineered to match OEM specifications for a precise fit and consistent braking performance.

Applications and Problem Solving

• Improves braking performance on Audi A1, Volkswagen Golf, Jetta, and other compatible models
• Reduces brake fade caused by heat buildup during aggressive or prolonged braking
• Helps prevent rotor warping and cracking through enhanced heat dissipation
• Minimizes rust and corrosion on the rotor hat for longer service life
• Maintains consistent braking feel with directional drilled and slotted design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (7 mm) before installation
• Clean mounting surface and hub to prevent uneven rotor seating
• Torque lug nuts to manufacturer specifications for secure fitment
• Check compatibility with vehicle make and model before installation
• Use proper brake pads designed for drilled and slotted rotors to optimize performance
