Hey folks

Ordered some aftermarket wheels, which I know the stock lugs aren't going to fit. Diameter of the head on the OEM bolts is too big. Knowing that, there are two solutions, one is the smaller diameter tuner lug bolts, another is the 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 5 Series F10 )

"Converting to wheel studs and lug nuts is a simple but highly effective work that can be completed in a few hours. Stud conversion offers an easier wheel mounting method, no more holding wheels a long time to align the bolts holes repeatedly, no more threading wheel hangers in and out which can be troublesome, no more worrying about scratching the brake calipers."

P.S. These pics comes from Webs.

Certainly make it easier mounting the wheels with studs. One word of caution make sure the new wheels are from a known source/manufacturer there have been many cases of after market wheels cracking.

Also while some larger sizes look better and fill the arches 21" and 22" rims do tend to restrict the tyres choices
