Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The black zinc coating on the hat area provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of drivers seeking reliable braking performance with enhanced durability for their Audi A4 and A4 Quattro vehicles.

Technical Specifications and Features

This disc brake rotor is a solid type with a nominal thickness of 10 mm and a discard thickness of 8 mm, ensuring a clear service limit for safe operation. The rotor measures 245 mm in outside diameter and 39.8 mm in overall height. It features a directional surface with both drilled holes and slots, which help to evacuate gases and debris from the braking surface, improving pad contact and reducing brake fade. The hat area is finished with a zinc black coating that provides rust resistance, important for maintaining rotor integrity over time. The rotor includes 5 bolt holes with a 112 mm bolt circle diameter, matching the stud/lug hole pattern of compatible Audi models.

Applications and Problem Solving

• Improves braking performance on Audi A4 and A4 Quattro vehicles
• Reduces brake fade during aggressive or repeated braking
• Helps prevent rotor warping caused by excessive heat
• Minimizes rust and corrosion on the rotor hat area
• Maintains consistent brake pad contact with slotted and drilled design

Installation Notes and Tips

When installing the Dynamite Friction 633-73043R rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the bolt hole pattern matches the vehicle’s hub (5 bolts, 112 mm bolt circle diameter). The directional surface should be installed following the rotation direction indicated on the rotor to maximize performance. Check rotor thickness before installation to confirm it is above the discard thickness of 8 mm. Proper torque specifications should be followed for all lug nuts to avoid rotor damage.
