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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on delivering rotors that combine cross-drilled holes and precision slots to enhance braking efficiency. This design helps maintain consistent brake pad contact, reduces gas buildup, and improves water dispersion. The vented rotor construction with pillar-style vanes further aids in heat management, making these rotors suitable for performance-oriented vehicles like the Nissan 350Z and Infiniti G35.

Technical Specifications and Features

These rotors feature a nominal thickness of 22.2 mm (0.874 inches) and a discard thickness of 20.2 mm (0.795 inches), ensuring durability and serviceability. The overall height measures 62.2 mm (2.449 inches), and the center hole diameter is 68 mm (2.677 inches), matching OEM specifications for proper installation. The rotors do not include ABS tone rings or bearings, and the disc mounting is of the floating/dih type, which allows for slight rotor movement to reduce stress and improve braking feel.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or track use
• Improves braking response and pedal feel on Nissan 350Z and Infiniti G35
• Helps prevent rotor warping caused by excessive heat buildup
• Minimizes brake dust and debris accumulation on rotor surface
• Enhances wet weather braking performance by dispersing water efficiently

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before 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 during rotor replacement
• Clean rotor surface with brake cleaner before installation to remove any protective coatings
• Check for compatibility with existing brake hardware as bearings and ABS tone rings are not included
