Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors are part of the StopTech Sport line, which focuses on delivering performance-oriented braking components suitable for both street and light track use. These rotors feature a slotted surface that helps maintain clean pad contact by channeling away dust, gas, and water, which can improve braking consistency under demanding conditions. The vented design with straight vanes enhances airflow through the rotor, reducing heat buildup and minimizing the risk of brake fade during extended use.

Constructed with a coated hat finish, these rotors resist corrosion, extending their service life and maintaining appearance. The floating disc mounting system allows for slight rotor movement, which helps prevent warping and ensures even pad wear. With an outside diameter of 350 mm and a nominal thickness of 30 mm, these rotors meet OEM specifications for the Nissan Armada and Infiniti QX56, ensuring proper fit and function.

Applications and Problem Solving

• Improves braking performance on Nissan Armada and Infiniti QX56 models
• Reduces brake fade during heavy or repeated braking
• Minimizes rotor warping and uneven pad wear
• Enhances heat dissipation for longer rotor life
• Maintains consistent brake pad contact with slotted surface

Installation Notes and Tips

Ensure compatibility with your specific vehicle model and year before installation. The rotors are designed for vehicles with 6 lug holes and a 140 mm bolt circle diameter. No bearings or ABS tone rings are included, so retain existing components if applicable. Proper torque specifications should be followed when mounting the rotors to avoid damage or misalignment. It is recommended to inspect brake pads and hardware during rotor replacement to ensure optimal braking system performance.
