Oh. So If I understand correctly, most german cars have lug studs that can be removed, or threaded into the hub to be taken out, while ours are fixed into the hub.
yes. pretty much.
Therefore, even with this adapter, the original 4x114 lug studs from our car would be sticking out as well as the 4x100 studs from the adapter.
yes. but just not as far, but far enough to not work with a flat hubbed wheel.
But how long are our studs? Couldn't getting a thicker adapter to cover them solve this problem? And getting a proper set of lug nuts to affix the adapter to the hub?
the lug nuts you see on the adapter in you link are the ones you use to put the adapter on our wheel studs. THEN you use whatever lug nuts you want on the wheel studs on the adapter. idk how long our studs are, but i doubt they make an adapter thick enough to fully incase them. at that point youll need to worry about making your car a widebody more than the stock wheel studs hitting the back of the wheels you want to put on.
honestly, id just go with the correct lug pattern wheel, itd make things a lot easier.if they dont make the wheel in the pattern, you can always have it redrilled, if thats an option with the design of the wheel, or youll just have to find something else......or you could always get in touch with the manufacturer and see if theyre custom one off you a set.
