Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor is designed to meet the specific braking needs of Acura and Honda vehicles, including the Accord and CL. The rotor’s vented construction features straight vanes that promote efficient airflow, helping to dissipate heat generated during braking. The cross-drilled and slotted surface enhances pad bite and helps evacuate gases and debris, which can improve braking consistency and reduce the risk of brake fade during aggressive driving or heavy use.

The rotor has a coated hat finish that provides protection against corrosion, extending the rotor’s service life. With a floating disc mounting design, this rotor accommodates thermal expansion and contraction, reducing the risk of warping. The precise dimensions, including a 10.236-inch outside diameter and a nominal thickness of 0.906 inches, ensure proper fitment and performance on compatible Acura and Honda models.
