Detailed Product Features and Specifications

This StopTech Sport Cross-Drilled Disc Brake Rotor features a vented design with straight vanes that promote efficient airflow to dissipate heat during braking. The cross-drilled surface pattern helps to reduce gas buildup and water accumulation, improving brake pad contact and performance. The rotor’s hat is coated to resist corrosion, extending the rotor’s service life. With a nominal thickness of 22 mm and a discard thickness of 20 mm, this rotor maintains structural integrity and safety standards. The overall height measures 36 mm, and the center hole diameter is 68 mm, ensuring proper fitment on the Audi S4 hub assembly. The floating disc mounting design allows for thermal expansion, reducing the risk of warping under high temperatures.
