Technical Specifications and Features

This disc brake rotor has a nominal thickness of 25.0 mm and a discard thickness of 23.0 mm, ensuring it maintains structural integrity throughout its service life. The rotor's outside diameter measures 311.9 mm (12.280 inches), with an overall height of 47.2 mm. It features a 5-lug bolt pattern with a 120 mm bolt hole circle diameter and 14.5 mm stud/lug hole diameter, matching Acura RLX factory specifications. The rotor hat is coated to resist rust and corrosion, and the smooth surface type promotes even brake pad wear. The vented design improves heat dissipation during braking, reducing the risk of brake fade. This rotor uses a floating disc mounting style, which helps accommodate thermal expansion and contraction.
