While other members can comments on the engineering aspect of lug bolts vs. nuts I’ll limit my reply to the following:

A. There is a tool kit, came in with my car. A metal threaded rod with plastic cover which I use to hang the wheel from the top hole. Pretty handy so it gives me the chance to get the other lug bolts on. It does make life easier. Note the front hub also start rotating while I am hugging the wheel to put it on; not the best feeling either.

B. Using bolts, I think, makes the discs replacement easier. They don’t get so rusty when compared with the nuts over studs setup.

C. Also and probably there is a cost factor: on BMWs you are dealing with 2 pieces only (threaded holes in a disc plus a lug bolt) where others use 3-5 more pieces (the disc, hole, pressed bolts, nuts etc) Cost factor? Convenience, anti hernia counter measure to us? possibly to our mechanics?

D. The only thing I don’t like about it is when I try to get those 17”rims out; they feel like someone got them welded to the hub. The amazing part? It doesn’t happen with the stock 15’ ones.

Are there any advantages from an engineering point view? Strength, stress and breaking points etc) I don’t know used used

My only guess is studs can break off. They can be repaired though.
