Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow to cool the rotor during braking. The drilled and slotted surface helps evacuate gases, dust, and water, improving brake pad contact and reducing the risk of glazing. The rotor has a nominal thickness of 30 mm and a discard thickness of 28 mm, ensuring safe replacement intervals. The rotor's overall diameter is 345 mm with a height of 52 mm, and it includes 5 bolt holes with a 112 mm bolt circle diameter, matching the factory specifications for the listed Audi and Porsche models.

Applications and Problem Solving

• Compatible with Audi A6, A6 Quattro, A7 Quattro, Porsche Macan, Q5, S4, and S5 models requiring vented rotors
• Addresses brake fade caused by overheating during aggressive driving or towing
• Reduces brake dust accumulation and improves pad bite with slotted and drilled surface
• Helps prevent rust and corrosion with zinc silver coated rotor hat
• Maintains braking performance in wet conditions by channeling water away from the rotor surface

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28 mm before installation. The rotor is directional, so proper orientation during installation is critical for optimal performance. Verify the 5-bolt hole pattern with a 112 mm bolt circle diameter matches your vehicle’s hub. Clean the rotor surface of any protective coating before mounting brake pads to avoid contamination.
