Product Description
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
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. bullet nose feature allows easy starting for lug nuts - in hot pit situations they can be air-gunned on.
