DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with enhanced surface features such as drilled holes and slots to improve heat dissipation and reduce brake fade. The zinc silver hat finish provides corrosion resistance, extending rotor life. This product line focuses on delivering reliable braking performance for specific Audi Quattro models with precise fitment and durability.

Detailed Product Description

This Dynamite Friction disc brake rotor is a solid type rotor with a directional surface featuring both drilled holes and slots. The drilled and slotted design helps to evacuate gases, dust, and water from the braking surface, improving braking consistency under demanding conditions. The rotor has a nominal thickness of 10 mm and a discard thickness of 8 mm, ensuring safe replacement intervals. The zinc silver hat finish combined with a rust-resistant coating protects against corrosion, which is critical for maintaining rotor integrity over time. With 4 bolt holes and a bolt circle diameter of 108 mm, this rotor is engineered to fit Audi 90 Quattro, 4000 Quattro, and Coupe Quattro models precisely.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Audi 90 Quattro, 4000 Quattro, and Coupe Quattro
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Restores braking performance compromised by rust or corrosion
• Maintains consistent braking under wet or dusty conditions with slotted and drilled design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (8 mm) before installation
• Clean mounting surface and hub to prevent rotor runout
• Torque bolts to manufacturer specifications for secure fitment
• Check compatibility with Audi 90 Quattro, 4000 Quattro, and Coupe Quattro models prior to installation
• Inspect brake pads for wear and replace if necessary to optimize rotor performance
