All sizes are made with aircraft quality alloy steel and have roll formed threads for greater strength than cut threads. We use a dry film lubricant HM-30 coating containing Teflon & Moly over a manganese phosphate finish. Manganese is preferred over the more common zinc because it's better at reducing friction and wear to prevent thread galling. With the dry lube applied over the phosphate this is the best corrosion resistance we have seen in any wheel stud! Salt tests have shown this stud is superior to others in corrosion resistance. The dry lube helps the nut engage and glide over the threads for faster engagement without cross threading or binding. Other features of our MSI studs include a large bullet nose nut-starter and a properly sized shank to work with a wider range of BMW wheel, nut, and brake rotor combinations. We intentionally avoid the extra large shoulders you see on other studs because they can interfere with some brake rotor hats. The extra large shoulder can be too large to allow the rotor to pass through and drilling out the holes is required (not cool!) Our studs have the sufficient shank for the brake rotor without interfering.
These studs are the perfect choice for endurance racers, sprint racers, track-only cars, or even hardcore street cars. The bullet nose on this stud is deeper than other studs we have used. More of the stud protrudes through the open nut so that everything lines up better on the threads. This helps to eliminate the possibility of cross-threading or thread stripping. In addition, the shank has been machined for proper brake rotor alignment. The dry lube helps the nut engage and glide over the threads for faster pit stops without cross threading or binding.
