Premium Race Bulletnose 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:

• Larger diameter shoulder for the stud to bottom out on, instead of allowing the threaded section to bottom in the sharp threads
• 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

M12x1.5 for BMW and other fitments. Heat treated 190,000psi Chromoly-steel, shot-peened, and double magnaflux inspected. This is a true professional quality stud. Bulletnose feature allows easy starting for lug nuts - in hot pit situations they can be air-gunned on.

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

Fits all 3 Series and other M12 lug BMWs (excludes X5/X6, late 7 Series and some other new large models).
