AIT Motorsport wheel studs are trusted by world-class race teams for their uncompromising strength, precision engineering, and motorsport-ready design. Converting from factory wheel bolts to studs not only improves safety but also allows for faster, more secure wheel changes — essential for both trackday drivers and competition use.

Featuring a bullet nose tip for quick wheel alignment and a distinctive motorsport look, AIT studs are available in a variety of thread options and lengths to suit multiple platforms including BMW, Porsche, and other performance vehicles.
