Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed to provide consistent braking performance for Mazda 3, Mazda 3 Sport, and Mazda 5 vehicles. The vented rotor design incorporates straight vanes that facilitate efficient airflow, helping to dissipate heat generated during braking. The cross-drilled and slotted surface improves pad bite and helps evacuate gases, dust, and water from the rotor surface, which can enhance braking response and reduce the risk of brake fade.

The rotor features a coated hat finish that protects against corrosion, extending the rotor's service life. The floating disc mounting design allows for slight movement between the rotor and hub, which can help reduce stress and improve rotor longevity. With a nominal thickness of 25 mm and a discard thickness of 23 mm, these rotors meet strict specifications to ensure safe and reliable braking performance.
