Parts Spotlight: Wheel Studs and Lug Nuts

Longer studs help endurance racers make wheel changes more quickly and securely.

(For all parts spotlights, click here.)

Endurance racing requires quick wheel changes, often in less than ideal conditions – at night, in the rain, etc. Mazda offers a variety of longer wheel studs with a quick start nose.  This enables the wheel to be removed and replaced much faster when compared to a stock wheel stud. Also, the rounded nose self-aligns the lug nut for easier installation with less risk of cross-threading.

According to MSI, MSI’s wheel stud/lug nut combination has consistently proven to be the quickest way off pit road.  MSI’s product line has evolved as a result of direct input from many of NASCAR’s leading teams. Understanding the needs of the NASCAR community and offering flexibility is what has set MSI apart from other manufacturers.

In addition to its proven NASCAR product line, MSI Racing Products has been producing Metric Styled wheel studs to meet the ever growing needs of sports car racing and after market wheels. Its products are being used in IMSA, SRO, SCCA, NASA, & other forms of professional and club racing.
