Stoptech 127.33079R Disc Brake Rotor - Front Right

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Overview

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (Part Number 127.33079R) are engineered for Porsche Cayenne and Volkswagen Touareg models. These vented rotors feature a slotted and drilled surface designed to improve braking performance and heat dissipation under demanding conditions.

• Cross-drilled and slotted rotor surface for enhanced cooling and debris removal
• Vented design with curved vanes to optimize airflow and reduce brake fade
• Coated hat finish to resist corrosion and extend rotor life
• Floating disc mounting for improved thermal expansion management
• Precision fit with 5 lug holes and 130 mm bolt circle diameter

Detailed Product Features and Specifications

This disc brake rotor has an outside diameter of 330 mm (12.992 inches) and an overall height of 69 mm (2.717 inches), making it compatible with the braking systems of Porsche Cayenne and Volkswagen Touareg vehicles. The rotor thickness is nominally 32 mm (1.260 inches) with a discard thickness of 30 mm (1.181 inches), ensuring safe replacement intervals. The rotor features a vented design with curved vanes that promote efficient heat dissipation during braking, reducing the risk of brake fade. The slotted and drilled surface helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and performance. The hat section is coated to protect against rust and corrosion, which is critical for maintaining rotor integrity over time.

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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance for sport and performance vehicles. This product line focuses on improving heat management and brake pad bite through precision machining of slots and drilled holes. The rotors are vented with curved vanes to optimize airflow, which helps maintain consistent braking under high-stress conditions. This makes them suitable for drivers who require reliable stopping power in both daily driving and spirited driving scenarios.

Applications and Problem Solving

• Compatible with Porsche Cayenne and Volkswagen Touareg models requiring 330 mm rotors
• Reduces brake fade caused by excessive heat buildup during aggressive driving
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust accumulation for cleaner braking components
• Helps prevent rotor warping through efficient heat dissipation

Installation Notes and Tips

• Ensure rotor discard thickness of 30 mm is not exceeded before replacement
• Verify 5 lug hole pattern and 130 mm bolt circle diameter for proper fitment
• Use proper torque specifications for mounting bolts to avoid rotor distortion
• Check compatibility with existing brake pads and calipers on Porsche Cayenne or Volkswagen Touareg
• Inspect rotors for damage or uneven wear during installation
