StanceMagic M12x1.5 Extended Wheel Stud Conversion Kit — BMW (Pack of 20)

StanceMagic builds these studs from cold-forged Grade 10.9 steel — a step above standard hardware — then adds a secondary heat treatment process to push strength and fatigue resistance even further. Machine-cut threads on both the vehicle-side and wheel-side ends ensure precise, rattle-free engagement with your hub and lug nuts. The black zinc coating rounds things out with reliable protection against corrosion, road salt, and surface scratches, keeping the hardware looking clean long after installation.

Fitment covers a wide sweep of BMW E-chassis models produced prior to 2012, including the 128i, 135i, the full E46 and E90 3 Series lineup, 5 Series models from the 525i through the 550i, the M3, M5, M6, Z3, Z4, 6 Series, and the 8 Series classics — plus the 2002–2005 Mini Cooper. These studs are specifically designed for European vehicles running M12x1.5 lug bolts, so always confirm your year and model before ordering. At 74mm total length with a 57mm shank, they provide proper thread engagement without requiring spacers on most standard applications.

Installation requires an allen wrench or hex key, torque wrench, and socket — tools most home mechanics already own. Apply thread-locking fluid to the short hub-side threads, torque each stud to 20 ft-lb, and torque your lug nuts to OEM spec once the wheel is on. StanceMagic recommends a re-torque of all hardware after the first 25–50 miles as a safety precaution, and professional installation is advised if this is your first stud conversion. Note that lug nuts are not included — visit BimmerTalk.com for compatible options in multiple styles and finishes.
