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

The StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on delivering rotors with enhanced thermal management and durability. The cross-drilled surface pattern improves heat dissipation and helps reduce brake fade during aggressive driving. The vented design with pillar-style vanes promotes airflow to maintain optimal rotor temperature. This product line is suitable for performance-oriented vehicles like the Nissan 350Z and Infiniti G35, providing reliable braking under spirited driving conditions.

Technical Description and Specifications

This disc brake rotor features a vented design with pillar-style internal vanes that facilitate efficient heat dissipation, reducing the risk of warping during heavy braking. The cross-drilled surface enhances water and gas evacuation from the rotor face, improving brake pad contact and performance. The rotor’s hat is coated to resist corrosion, extending service life. With a floating disc mounting design, the rotor allows slight movement to accommodate thermal expansion and reduce stress. The rotor measures 324 mm in outside diameter and has a nominal thickness of 30 mm, with a discard thickness of 28.4 mm, ensuring clear service limits for maintenance.

Applications and Problem Solving

• Improves braking performance on Nissan 350Z and Infiniti G35 models
• Reduces brake fade during high-temperature conditions
• Minimizes rotor warping and cracking under aggressive use
• Enhances water and debris evacuation for consistent braking
• Provides corrosion resistance for longer rotor life

Installation Notes and Tips

• Ensure compatibility with Nissan 350Z and Infiniti G35 before installation
• Check rotor thickness and discard limits during installation
• Use proper torque specifications for the 5 lug bolts on the 114.3 mm bolt circle
• Inspect brake pads and calipers for wear or damage when replacing rotors
• Follow manufacturer guidelines for bedding-in new rotors and pads
