Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to enhance airflow and heat dissipation during braking. The rotor's nominal thickness is 0.709 inches (18.000 mm), with a discard thickness of 0.630 inches (16.000 mm), ensuring clear service limits for safe operation. The overall height measures 1.772 inches (45.000 mm), and the outside diameter is 9.240 inches (234.700 mm). The rotor includes four stud/lug holes with a diameter of 0.512 inches (13.000 mm) and a mounting bolt hole circle diameter of 3.937 inches (100.000 mm). The center hole diameter is 2.165 inches (55.000 mm). The smooth surface finish promotes consistent brake pad contact, while the floating disc mounting allows for slight movement to reduce stress and improve rotor longevity.
