BMS wheel stud conversion kit for BMW (M12x1.5)

Replace factory wheel bolts with wheel studs? Every BMW enthusiast knows the feeling of trying to hold the wheel in place while threading the bolts — one slip away from a dropped wheel and instant horror movie. Wheel studs make wheel changes faster, easier, and far more controlled.

These M12x1.5 wheel studs fit most BMW E-series models. With a 90 mm total length, they also allow the use of a small wheel spacer when needed.

Manufactured in Italy from high-quality 10.9 grade steel, each stud is x-rayed for quality control and finished with an OEM-style black zinc coating. Genuine European manufacturing and motorsport-level quality you can trust.
