StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Product Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on delivering rotors that combine enhanced cooling capabilities with improved pad bite and debris removal. The cross-drilled holes and slots work together to maintain consistent braking performance by reducing heat buildup and preventing gas and dust accumulation on the rotor surface. This product line is designed for drivers who require reliable braking performance on both street and light track use, making it suitable for performance-oriented Audi and Volkswagen vehicles.

Detailed Product Description

These StopTech rotors feature a vented design with pillar-style vanes that promote airflow through the rotor, helping to dissipate heat more efficiently during braking. The slotted and cross-drilled surface improves pad bite and helps clear away brake dust and gases, which can otherwise reduce braking effectiveness. The coated hat finish protects against corrosion, extending the rotor's service life. With a floating disc mounting system, the rotor can better accommodate thermal expansion and reduce the risk of warping. The rotor's dimensions, including a 13.386 inch (340 mm) outside diameter and 1.181 inch (30 mm) nominal thickness, ensure compatibility with specified Audi and Volkswagen models.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or towing
• Improves heat dissipation for consistent braking performance
• Minimizes brake dust and gas buildup on rotor surface
• Prevents rotor warping through floating disc design
• Protects against corrosion with coated hat finish

Installation Notes and Tips

• Ensure compatibility with your specific Audi or Volkswagen model before installation
• Check rotor thickness and discard limits to confirm suitability
• Use proper torque specifications for the 5-lug mounting pattern with 4.409 inch bolt circle diameter
• Inspect brake pads and calipers during rotor replacement for optimal performance
• Follow manufacturer guidelines for bedding-in new rotors and pads
