Product Features and Specifications

The StopTech Sport Cross-Drilled Disc Brake Rotors feature a vented design with straight vanes that promote efficient airflow to maintain optimal operating temperatures. The cross-drilled surface helps to dissipate heat and gases generated during braking, reducing the risk of brake fade under heavy use. The coated hat finish protects against rust and corrosion, extending rotor life. These rotors have a nominal thickness of 1.181 inches (30.000 mm) and a discard thickness of 1.102 inches (28.000 mm), ensuring safe replacement intervals. The overall diameter measures 12.992 inches (330.000 mm) with an overall height of 2.165 inches (55.000 mm). The rotor mounts using a floating disc system with a 6-stud lug hole pattern and a mounting bolt hole circle diameter of 5.531 inches (140.500 mm).
