M14 Premium 92mm BimmerWorld Race Bullet Nose Wheel Stud

This new wheel stud is made exclusively for BimmerWorld by one of America's leading manufacturers of race fasteners to our exacting specifications. Wheel studs are not a one time purchase and do fatigue with torque cycles and use, however we have noticed shorter lifespans than expected in our race program with other studs. Further analysis showed stress risers created by screwing studs into the steel hub flange. We have addressed this issue in several ways:

• Large shoulder provides extra strength and is properly sized for BMW brake rotor hats
• Undercut relief to remove thread run-out section of stud that the steel hub would otherwise cut into
• All corners radiused to eliminate stress risers

M14x1.25 for BMW F-chassis. Heat treated 190,000psi Chromoly-steel, shot-peened, and double magnaflux inspected. This is a true professional quality stud. bullet nose feature allows easy starting for lug nuts - in hot pit situations they can be air-gunned on. Uses M14x1.5 wheel nut. M2CS and M4 GT4 will no longer use their factory M12 wheel nuts.

Available in 73mm, 82mm or 92mm total length includes bullet nose and threads into hub using a "Dri-Loc" locking adhesive for an extremely secure fit.

Wheel studs for all F-chassis M2, M3, M4, M5, and M6 as well as non-M 2-series, 3-series, 4-series, 5-series, 6-series, 7-series, X-series, and Z-series that use the 14x1.25 bolt thread (BMW #36136781151 or 36136774896). Also fits E70 X5 and E71 X6.

• Hub thread length - 14mm
• Nut thread length (to hub face) - 60mm
• Hub face to stud nose - 78mm 
   

Even though the stud threads into the 14x1.25 hub (like the factory bolts), the wheel-side of the stud is 14x1.5 thread size. The coarser thread is faster and 14x1.5 nuts are more easily available.

“What is the BMW wheel nut torque?” Our torque spec for M14 wheel nuts (not bolts) is 90ft-lbs done when the nuts and wheel are cold (ambient temp). Do not torque when the nuts are hot and do not exceed 90ft-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.

Product Note: These wheel studs are intended for track/race applications where frequent wheel changes occur. These studs do not have a cosmetic finish applied. If used on street applications, especially in the winter, light surface oxidation/discoloration may occur. If your intent is for street use we recommend using our street line of studs.
