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 rotor surface technology. The combination of cross-drilled holes and precision slots helps to reduce brake fade by allowing gases and heat to escape more efficiently. This rotor line features a vented design with straight vanes to maintain optimal operating temperatures during demanding driving conditions. The coated hat finish offers additional protection against corrosion, making these rotors suitable for both daily driving and spirited use on Nissan trucks and SUVs.

Technical Specifications and Features

These disc brake rotors have a nominal thickness of 1.024 inches (26.0 mm) and a discard thickness of 0.945 inches (24.0 mm), ensuring a reliable service life before replacement is necessary. The overall height measures 1.543 inches (39.2 mm), and the center hole diameter is 3.937 inches (100.0 mm). The rotors mount behind the hub using a 6-bolt pattern with a 1.250 thread pitch, compatible with the specified Nissan models. The vented rotor design with straight vanes promotes consistent airflow to reduce heat buildup during braking.

Common Applications and Problem Solving

• Improves brake cooling to reduce fade during heavy braking
• Helps prevent rotor warping caused by excessive heat
• Enhances brake pad bite and debris removal with slotted and drilled surface
• Reduces corrosion on the rotor hat area with coated finish
• Maintains consistent braking performance for Nissan 720, D21, Frontier, Pathfinder, and Pickup front brakes

Installation Notes and Tips

• Ensure compatibility with Nissan front brake systems before installation
• Inspect mounting bolts and hardware for wear or damage during rotor replacement
• Torque mounting bolts to manufacturer specifications to avoid rotor distortion
• Check brake pads for wear and replace if necessary to optimize rotor performance
• Perform a proper bed-in procedure after installation to maximize braking efficiency
