Detailed Product Specifications

This StopTech rotor features a vented design with straight vanes to optimize airflow and cooling during braking. The cross-drilled and slotted surface pattern helps to evacuate gases, dust, and water, maintaining consistent pad contact and reducing brake fade. The rotor has a nominal thickness of 0.945 inches (24 mm) and a discard thickness of 0.866 inches (22 mm), ensuring a long service life before replacement is necessary. The overall height measures 2.228 inches (56.6 mm), with a center hole diameter of 2.283 inches (58 mm) and a mounting bolt hole circle diameter of 100 mm (3.937 inches). It includes five stud/lug holes with a diameter of 0.508 inches (12.9 mm) and features a floating disc mounting system to accommodate thermal expansion and improve braking consistency. Weighing approximately 14 lbs (6.36 kgs), this rotor balances durability and performance.

StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors Line

The StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance for sport and daily driving applications. This product line focuses on improving heat dissipation and pad bite through cross-drilled holes and slots, combined with vented rotor construction.
