Detailed Product Features and Specifications

This StopTech rotor is a vented type with straight vanes, which helps to efficiently dissipate heat generated during braking. The cross-drilled and slotted surface design reduces brake fade by allowing gases and debris to escape, improving pad bite and overall braking consistency. The rotor’s coated hat finish provides protection against rust and corrosion, extending the service life of the part. It features a 5-bolt mounting pattern with a bolt circle diameter of 111.1 mm (4.374 inches) and mounting bolt holes sized at 11.5 mm (0.453 inches). The center hole diameter measures 82.6 mm (3.252 inches), ensuring proper alignment behind the hub.
