Detailed Product Description

The StopTech Sport Cross-Drilled Disc Brake Rotors feature a vented design with pillar-style vanes that promote optimal airflow to reduce heat buildup during braking. The cross-drilled surface pattern enhances water and gas evacuation, improving brake pad contact and reducing fade. The rotor’s coated hat finish provides corrosion resistance, helping maintain structural integrity over time. With a nominal thickness of 22.2 mm (0.874 inches) and a discard thickness of 20.2 mm (0.795 inches), these rotors meet strict specifications for durability and performance. The 5-lug hole pattern with a 114.3 mm bolt circle diameter ensures proper fitment on Nissan 350Z and Infiniti G35 models. The floating disc mounting system allows for controlled rotor movement, reducing stress and improving braking consistency.

StopTech Sport Cross-Drilled Disc Brake Rotors Product Line

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to provide enhanced braking performance for sport and performance vehicles. This product line focuses on improving heat dissipation and reducing brake fade through cross-drilled surfaces and vented rotor designs. The rotors are engineered to maintain structural integrity under high thermal loads, making them suitable for spirited driving and track use while maintaining compatibility with OEM specifications.

Common Applications and Problem Solving

• Reduces brake fade during aggressive driving or track conditions
• Improves heat dissipation to prevent rotor warping
• Enhances wet weather braking performance by evacuating water
• Minimizes corrosion with coated hat finish for longer service life
• Provides consistent pedal feel and stopping power for Nissan 350Z and Infiniti G35

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (20.2 mm) before installation
• Use proper torque specifications for the 5-lug mounting pattern (114.3 mm bolt circle)
• Inspect brake pads and calipers for wear or damage during rotor replacement
• Clean rotor surface with brake cleaner before installation to remove any protective coatings
• Check for ABS sensor clearance as these rotors do not include an ABS tone ring
