"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 their 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. Their products are currently being used in IMSA, World Challenge, SCCA, NASA, & other forms of professional and club racing." -msirp.com

Why we like MSI studs:

• High Quality machined components
• graphite baked on for reduction in galling
• bull nose for ease of starting lug nuts
• nuts are yellow, easy to see

These MSI  studs are OEM length PLUS 12mm. They are not EXTRA long. If you run a small spacer, you will have enough thread engagement. If you need to run hub-centric spacers, you will need ARP PN 100-7713 (no bullnose) or ARP 100-7731 (Bullnose) which are 25mm longer~
