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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide improved braking performance through enhanced heat dissipation and pad bite. The combination of cross-drilled holes and precision slots helps to evacuate gases, dust, and water from the rotor surface, which is critical for maintaining consistent braking on Audi Cayenne, Porsche Cayenne, Volkswagen Touareg, and Audi Q7 vehicles. The vented rotor design with straight vanes further aids in cooling, reducing the risk of brake fade during extended use.

Detailed Product Description

This disc brake rotor (Part Number 127.33078R) is a vented type rotor featuring a slotted and drilled surface to optimize braking efficiency. The rotor’s overall height measures 73.7 mm (2.902 inches), and it includes two miscellaneous holes for mounting or balancing purposes. The coated hat finish protects against corrosion, extending the rotor’s service life. Designed with five lug holes spaced on a 130 mm bolt circle diameter, this rotor fits specific Audi, Porsche, and Volkswagen models requiring precise fitment. The rotor’s nominal thickness of 28 mm ensures durability, while the discard thickness of 26 mm indicates when replacement is necessary to maintain safe braking performance.

Common Applications and Problem Solving

• Improves braking response and reduces brake fade on Audi Cayenne, Porsche Cayenne, Volkswagen Touareg, and Audi Q7
• Helps dissipate heat more effectively during aggressive driving or towing
• Reduces brake pad glazing and buildup of debris on the rotor surface
• Minimizes risk of rotor warping caused by thermal stress
• Enhances wet weather braking performance by channeling water away from the rotor surface

Installation Notes and Tips

• Ensure compatibility with vehicle make and model before installation
• Check rotor thickness and discard thickness to confirm suitability
• Use proper torque specifications for lug nuts to avoid rotor damage
• Inspect brake pads and replace if worn to maximize rotor performance
• Clean rotor surface before installation to remove any protective coatings or contaminants
