Detailed Product Features and Specifications

This StopTech rotor features a vented design with straight vanes that promote airflow to maintain optimal operating temperatures. The cross-drilled surface pattern helps to evacuate gases and debris, improving brake pad contact and reducing the risk of brake fade during heavy use. The rotor’s hat is coated to resist corrosion, extending service life in various driving environments. With a floating disc mounting system, the rotor allows slight movement to accommodate thermal expansion and improve braking consistency.

Key dimensions include an outside diameter of 318.7 mm (12.547 inches), a nominal thickness of 28.0 mm (1.102 inches), and a discard thickness of 26.0 mm (1.024 inches). The center hole diameter measures 108.0 mm (4.252 inches), and the mounting bolt hole circle diameter is 139.7 mm (5.5 inches), designed for 6 lug holes each 14.4 mm (0.567 inches) in diameter. The rotor weighs approximately 9.55 kg (21 lbs), balancing durability and performance.
