• Overall diameter of 10.039 inches (255.000 mm) for precise fitment
• Floating disc mounting design with 5 lug holes (0.610 inches / 15.500 mm diameter)
• Compatible with Audi A6 Quattro and Allroad Quattro models

Detailed Product Description

The StopTech Sport Cross-Drilled Disc Brake Rotors are part of StopTech's Sport line, which focuses on delivering enhanced braking performance through advanced rotor design. The cross-drilled surface pattern improves ventilation and helps reduce brake fade by allowing heat and gases to escape more efficiently during braking. This rotor is solid rather than vented, providing a consistent braking surface optimized for street and light performance use.

With a coated hat finish, the rotor resists rust and corrosion, maintaining structural integrity and appearance over time. The rotor's overall height measures 1.882 inches (47.800 mm), and it features a center hole diameter of 2.677 inches (68.000 mm) to ensure proper alignment and fitment. The mounting bolt hole circle diameter is 4.409 inches (112.000 mm), accommodating 5 lug holes, which matches the factory specifications for the compatible Audi models.

Applications and Problem Solving

• Replaces worn or warped rotors on Audi A6 Quattro and Allroad Quattro
• Addresses brake fade caused by excessive heat buildup during spirited driving
• Improves brake pad bite and responsiveness with cross-drilled surface
• Prevents corrosion-related rotor damage with coated hat finish
• Restores proper rotor thickness and braking efficiency

Installation Notes and Tips

• Ensure rotor thickness is within discard limits (minimum 0.315 inches / 8.000 mm) before installation
• Verify compatibility with Audi A6 Quattro and Allroad Quattro models using part number 128.33064L
• Use proper torque specifications for lug nuts to avoid rotor warping
• Inspect brake pads and replace if worn to maximize rotor performance
• Clean rotor surface before installation to remove any protective coatings or contaminants
