Detailed Product Features and Specifications

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors feature a vented design with straight vanes that promote effective airflow, helping to keep the rotor cool during demanding driving conditions. The rotor measures 10.118 inches (257 mm) in outside diameter with an overall height of 1.799 inches (45.7 mm). The nominal thickness is 0.965 inches (24.5 mm), with a discard thickness of 0.882 inches (22.4 mm), ensuring a clear service limit for safe operation.

The rotor surface is cross-drilled and slotted to improve brake pad bite and reduce the buildup of brake dust and gases. The hat section is coated to protect against rust and corrosion, which is especially beneficial for vehicles exposed to harsh weather conditions. This rotor uses a floating disc mounting system and includes four mounting bolt holes with a 4.5-inch (114.3 mm) bolt circle diameter, designed for a 4-lug pattern with 0.5-inch (12.7 mm) diameter holes.

About the StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Line
