MSI's wheel stud/lugnut 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 our 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 aftermarket wheels. Our products are currently being used in IMSA, World Challenge, SCCA, NASA, & other forms of professional and club racing.
