MSI M12x1.5 Coated Wheel Studs

M12x1.5 studs are used on the majority of BMWs from the E9X and earlier chassis.  Later “F” chassis models typically use M14x1.5 nuts and studs.

Choosing the correct length: As a general guideline, the 85.5mm studs will allow for up to a 15mm spacer on most wheels and the 74.5mm studs will allow for up to a 5mm.  The 95.5mm studs are recommended for when a 20mm spacer is used.  These fitments have been tested on E46 and E36 chassis with Apex, Forgeline, and BimmerWorld 17×9 wheels.

Installation: Install using high strength (red) thread locker.  Only torque to 20 ft-lb into the hub.  Use double nut method for installation, do not reuse these nuts to secure wheel.

Use: The coating on these studs allows for less wheel installation torque.  We recommend a torque setting of 70 ft-lb when using both coated MSI studs and lug nuts.  Always recheck your wheel torque after allowing the wheel to cool.
