These Premium Race Wheel Studs and Nuts are what serious racers and track enthusiasts want for wheel mounting. These studs have greater strength and durability than our standard Street studs - especially when subjected to repeated abuse from impact guns. While our standard studs work great for the casual enthusiast and the occasional track day, small details in a Premium stud are appreciated when taking your car to the next level or beyond. 73mm studs work with no spacers with full nut engagement.
Racing conditions mean studs take a lot more abuse than seen on a typical street application. Our Premium Bullet Nose wheel studs are simply stronger and a higher grade than standard studs. Our stud specs are truly impressive: heat-treated, 12.9 grade, high-tensile 190,000 psi strength, Chromoly steel, which is shot-peened for additional strength and individually double magnaflux inspected. Additional design features help prevent the typical stress risers caused by threading the stud into a steel hub. The threads are phosphate and oil coated, and are rolled instead of cut which results in a smoother engagement with fewer imperfections. Anaerobic threadlocker is pre-applied which eliminates the need for additional Loctite. The black wheel nuts are zinc coated to resist corrosion, and they have a M14x1.5 thread and 60 degree taper to fit all BMW-applicable wheels.

“What is the BMW wheel nut torque?” Our torque spec for wheel nuts (not bolts) is 75ft-lbs done when the nuts and wheel are cold (ambient temp). Do not torque when the nuts are hot and do not exceed 75ft-lbs. Remember that nuts - and studs - are consumables and should be inspected and replaced periodically. See our instructions link above for complete stud and nut installation guidelines.
