Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Black from Dynamite Friction is designed to meet the specific braking requirements of select Audi models. Its vented design improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power. The rotor’s surface is both drilled and slotted, allowing for efficient removal of brake dust, gases, and water, which can improve brake pad contact and reduce fade under demanding conditions.

Constructed with a plain disc finish and a zinc black coated hat, this rotor offers corrosion resistance to extend service life. The rotor’s dimensions, including a 320 mm outside diameter and 52.2 mm overall height, are engineered to match factory specifications for a direct replacement. The 5-bolt hole pattern with a 112 mm bolt circle diameter ensures proper fitment on compatible Audi vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Audi A4, A4 Quattro, A5, A5 Quattro, and Q5
• Improves brake cooling to reduce fade during heavy braking
• Helps eliminate brake pad glazing and uneven wear
• Reduces brake dust accumulation for cleaner braking surfaces
• Addresses corrosion issues with rust-resistant coating

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28 mm before installation. Clean the rotor surface to remove any protective coating or contaminants prior to mounting. Verify the 5-bolt hole pattern and 112 mm bolt circle diameter match your vehicle’s hub. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.
