About the StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to enhance braking performance by combining cross-drilled holes and precision slots. This design improves heat dissipation and helps remove brake dust and gases from the rotor surface, which can improve pad bite and reduce brake fade. The vented rotor construction with straight vanes further aids in cooling, making these rotors suitable for both street and light performance driving applications.

Detailed Product Description

These disc brake rotors feature a vented design with straight vanes that promote airflow to reduce heat buildup during braking. The cross-drilled and slotted surface pattern helps maintain consistent braking performance by allowing gases and debris to escape, which can otherwise cause uneven pad contact. The coated hat finish protects the rotor’s central hub from corrosion, ensuring a longer service life. With a floating disc mounting style, the rotor can better accommodate thermal expansion and reduce the risk of warping. The rotor’s dimensions, including an outside diameter of 11.339 inches and a nominal thickness of 0.980 inches, are engineered to meet the specifications required for select Audi and Volkswagen models.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup during aggressive driving
• Improves braking response by maintaining cleaner rotor surfaces
• Minimizes rotor warping through vented design and floating mounting
• Protects against corrosion with coated hat finish
• Compatible with ABS systems that do not require tone rings

Installation Notes and Tips

• Ensure compatibility with your specific Audi or Volkswagen model before installation
• Check rotor thickness and discard limits to confirm suitability for replacement
• Use proper torque specifications for the 5-lug mounting pattern with 0.610 inch diameter holes
• Inspect brake pads and calipers during rotor replacement for optimal performance
• Do not reuse old hardware to maintain secure mounting and safety
