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

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-coated hat finish provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of performance-oriented braking while maintaining durability for daily driving conditions.

Technical Specifications and Features

This disc brake rotor is a solid type with a nominal thickness of 12 mm and a discard thickness of 10 mm, ensuring reliable wear limits. The rotor measures 255 mm in outside diameter and 39.8 mm in overall height, fitting precisely on compatible Audi A4 and A4 Quattro models. The rotor surface is both drilled and slotted, which helps to evacuate gases and debris from the braking surface, improving pad contact and reducing brake fade. The directional design of the braking surface optimizes airflow and cooling during operation.

Applications and Problem Solving

• Improves braking performance on Audi A4 and A4 Quattro vehicles
• Reduces brake fade caused by heat buildup during aggressive driving
• Helps prevent rotor warping and uneven pad wear
• Enhances water and debris evacuation for consistent braking in wet conditions
• Provides corrosion resistance to extend rotor lifespan

Installation Notes and Tips

Ensure the rotor is installed on vehicles matching the specified fitment: Audi A4 and A4 Quattro. Verify the bolt hole pattern of 5 holes with a 112 mm bolt circle diameter matches the vehicle hub. Clean the rotor surface before installation to remove any protective coatings or residues. Use proper torque specifications for lug nuts to avoid rotor distortion. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 633-73045R rotor with rust-resistant coatings and zinc black hat finish to enhance durability.
