APEX BMW 75mm Stud (Sold as an individual Stud), Black.
Nut is NOT included.
Studs also available as a complete kit (set of studs and nuts, see catalog).
Try and find a BMW race car that hasn't converted to studs yet. They're stronger, safer, and improve pit stop times significantly and just make it easier whenever you need to take off or change your wheels/tires.
For non race cars, stud conversions make wheel install and removal much easier as you do not have to line up the holes in your wheels, spacers, and hubs before hand threading in a single lug bolt. Simply slide the wheel onto the studs, and let go. Your wheel will no longer spin around the hub, but will instead be lined up correctly.
Extended length studs like these allow for a range of spacers to be used without any additional modification. You can easily use 3, 5, 10, 12, 18, 20, 25mm or no spacer at all. When using lug bolts with spacers you are forced to purchase a different length lug for each width spacer. Why own a bucket full of lugs when a single set of studs can do it all?
By remaining installed, the studs put less ware on the threads of your hubs. They guarantee there is enough thread engagement, as you can see how many threads were engaged during install.
Wheel studs replace your OEM lug bolts by simply threading into your cars hub. Once installed they do not need to be removed when changing or removing wheels. Only the lug bolts are removed similar to many domestic vehicles.
APEX Wheel studs are 10.9 grade steel, and produced in Europe by a TUV approved OEM supplier
75mm length allows for the use of spacers up to 12mm in thickness, or no spacer at all, without making any changes
The hardened studs are black zinc plated, while the nuts (NOT included w each stud, must be purchased as part of a kit or separately) are available in both black and silver zinc plating.
Studs and nuts are 12x1.5 thread with a 60 degree taper identical to OEM BMW hardware
These work on all 1, 3, Z series models, and every other BMW with a M12x1.5 lug except the F30 3 Series, F10 5 Series, X1, X3, X5, X6, newer 7 Series and any other that does not use M12x1.5.
Thread the studs into your hubs until they bottom out. You will have to double nut the studs to install them. Place 2 nuts on the stud and lightly lock them together. Be sure to use red Loctite or equivalent to properly secure the studs and prevent them from backing out. Do not torque studs like a traditional lug bolt. Torque them to 30 ft-lbs only. Lug nuts can then be torqued on at the regular BMW suggested rating of 80-88 ft-lbs.
You will also have to double nut the studs to remove them. Simply place 2 nuts onto a stud and light lock them together. This allows you to remove the stud by using the nut closest to the wheel.
