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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on performance-oriented rotors that combine cross-drilled holes and slots to optimize braking efficiency. This design enhances pad bite and helps evacuate gases and debris, which is critical for maintaining consistent braking on vehicles like the Nissan 350Z and INFINITI G35. The vented rotor construction further aids in heat management, making these rotors suitable for spirited driving and daily use.

Technical Specifications and Features

These rotors feature a nominal thickness of 0.630 inches (16.000 mm) and a discard thickness of 0.551 inches (14.000 mm), ensuring a long service life before replacement is necessary. The overall diameter measures 11.488 inches (291.800 mm), with a vented design incorporating straight vanes to improve airflow and cooling. The hat section is coated to prevent corrosion, and the rotor includes a center hole diameter of 2.677 inches (68.000 mm) with a 5-lug bolt pattern spaced on a 4.500 inch (114.300 mm) bolt circle diameter. Weighing approximately 12 lbs (5.450 kgs), these rotors balance durability with manageable unsprung weight.

Applications and Problem Solving

• Improves braking performance on INFINITI 350Z and Nissan G35 during aggressive driving
• Reduces brake fade caused by heat buildup on Nissan Rogue and Rogue Sport models
• Helps maintain consistent brake pad contact and bite on Nissan Juke and X-Trail
• Minimizes corrosion and extends rotor life in humid or coastal environments
• Addresses vibration and noise issues common with worn or warped rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of contaminants before installation. These rotors do not include bearings or ABS tone rings, so verify compatibility with your vehicle’s existing components. Proper torque specifications should be followed for the 5-lug mounting bolts to avoid warping. It is recommended to replace brake pads simultaneously to optimize braking performance and rotor longevity.
