BMW Z8 Tuning Work, Wheel Stud Conversion Kit

[Honkermaysa]

Hi all.
I've ordered some aftermarket wheels, which I know the factory lugs aren't going to fit. Diameter of the head on the OEM bolts is too big. Knowing that I should purchase a set of longer bolts or convert to a wheel stud conversion kit.

In fact, I am going to order a set of stud conversion now because the bolts are becoming a pain to use without a pin.
I also did some study of them. There are several advantages:

1.They offer an easy way to align the wheel when mounting;
2.They allow for the safe use of different thickness wheel spacers;
3.It is compatible with both ball and conical seat lug nuts, which is suitable for most factory or aftermarket wheels.
(Quoted from:Wheel Stud Conversion for BMW )

I am willing to buy a set of Titanium studs cause I learn that: "Titanium alloy materials, which possess high mechanical properties, not only have great fatigue strength and tensile strength performance but also maintain great strength at extreme temperatures up to 400 to 500°C. They are light in weight, also have extraordinary corrosion resistance."

P.S. These pics comes from Webs.

Studs + nuts are a better option that bolts. Mechanically, they are a much better clamping solution than bolts. Wheel bolts are in tension, bending, shear and thread shear at the wheel/hub interface. Wheel studs are in tension, bending and shear at the interface, but they are in thread shear around the nut.

The only downside is that the portion of stud thread that is being used is the "height" of the nut. Make sure that you use a suitably "thick" nut, or you may strip the threads, and there should be at least two threads showing after the nut is fully torqued.

Thanks for the info. Really useful.
