Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps to evacuate gases, dust, and water, improving braking consistency and reducing fade. The black zinc coating on the rotor hat enhances corrosion resistance, extending the rotor's service life in demanding conditions. This product line is tailored for drivers seeking reliable performance on Audi and Volkswagen vehicles requiring vented, directional rotors.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat effectively. The rotor's nominal thickness is 25 mm, with a discard thickness of 23 mm, ensuring safe replacement intervals. The rotor surface is finished plain, while the hat features a zinc black coating to resist rust. The rotor includes five bolt holes with a 112 mm bolt circle diameter and a center hole diameter of 68 mm, matching factory specifications for the listed Audi and Volkswagen models.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat during aggressive or prolonged braking
• Improves braking performance in wet conditions by channeling water away from the rotor surface
• Minimizes brake dust accumulation for cleaner braking components
• Prevents rust and corrosion on the rotor hat, extending rotor lifespan
• Maintains consistent braking feel on Audi A4, A6, Passat, and related Quattro models

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 23 mm before installation. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 112 mm bolt circle pattern. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 633-73041L rotor to meet OEM standards for fitment and durability. The rust-resistant zinc black coating on the rotor hat helps maintain structural integrity over time. While no specific warranty information is provided, this rotor is designed to comply with industry quality and safety requirements for Audi and Volkswagen brake components.
