ahh so its a spacer for the studs, makes sense.....
Something like this, my stock 318ci lug nut is M12, while the wheels itself is M14, i have to custom a lug nut spacer just to make sure the lug nut fit in the holes completely. Those spacers actually eliminated 90% of the vibration issue but my mechanic pre-amped me the tyres are too far out, almost stick out of the fender, so i will definitely feel some vibrations.
BMW doesn't have studs sticking out from the wheel hub, it uses nut to hold the wheels, so i think this is more like a lug nut spacer then stud, mine is totally custom make to cater my current wheels.
It was done without my knowledge and approval, i am going to other tyre shop that specializes in wheels and look for the specific hub centric ring for my case. Before i suspect my suspension components, might want to check cheaper fixes first.
This is the scary part, these people are supposed to be professionals. This is why I prefer DIY, at least I know its done right. I feel very hard to trust these so called profesionals with their "bolehlah" "cukuplah" "apalumaulagilah" attitude.
Well he kept the other unshaved ring for just in case, may be i should put that up and forcefully mount it on. Have to put some grease first before putting it up.
i think they are generally called 'stud spacers', stud is the extended bit, doesnt matter if its on the hub or bolt (the studs can just be screwed off the hub btw)

It looks like BMW OEM 166 style rim, but in 17 inch size. Previously before conversion was on BMW OEM 70 style with the wheels sit nicely within the arch and no vibration issues. The BMW OEM 166 supposing has ET28 offset which pushes the tyres further out from the wheel hub.

My issue is there's no hub centric ring suitable for either the car or rim. The vibrations happened on 160-180 km/h (electronic limited)
This is also my consideration, however, my wheels are already very far out and align with fender, if further away from the car body and i will need wide body kitu really need hubcentric
either like this to convert from bolt in M12 screw into M14 stud to fix the wheel
or use 1 big center cone to keep the wheel center in the hub along with those "m12 to m14 lugnut bushing"
I am doing this now, traded rims and tyre for another set of 18' rims and tyres. I am lucky enough to get it loan first before purchasing. Will be fitting it this month, wish me luck.
Yup, should be able to. Mine made of aluminum. If no size, the tyre shop can measure and get machine shop to machine a set for him. Earlier days I did that, nowadays most are ready made....
