Detailed Product Features and Specifications

This StopTech rotor features a vented design with straight vanes that promote efficient airflow, helping to maintain optimal braking temperatures during aggressive driving or heavy use. The cross-drilled and slotted surface improves pad bite and helps evacuate gases, dust, and water from the braking surface. The rotor has a coated hat finish to protect against rust and corrosion, extending its service life. With an outside diameter of 355 mm (13.976 inches) and a nominal thickness of 32 mm (1.260 inches), it meets OEM specifications for fit and function. The floating disc mounting system allows for slight movement between the rotor and hub, reducing the risk of warping under thermal stress. This rotor is designed with 5 lug holes on a 114.3 mm bolt circle diameter, compatible with the specified Nissan and Infiniti models.
