Wide [25mm] spacers should [in your example] be 8 hole...4 X 101.6 bolted to the Hub/original studs... nuts flush with the face of the spacer & a separate "offset" 4 X 101.6 PCD with a 2nd set of studs to suit the rims with appropriate nuts.
Confused yet??
Actually no, not confused. That's quite clearly explained. lol

The above leads to a conclusion that correctly lubricated and torqued wheel studs/nuts and clean bearing faces between wheels and hubs (or spaces and wheels and spacers and hubs) would be entirely satisfactory for cars that are driven on good roads.
Any failure to tension the studs correctly or excessive, damaging wheel impacts could well lead to the wheel moving on the hub and placing the studs in bending. Dowels, hub-centric locators, or short studs with cone/cylindrical mating faces are really a belt and braces back-up for correct installation of the wheels.
This is pretty much what i have been thinking from the outset. I was pretty sure that the force required to make a wheel slide on the face of the hub and spacer was quite high, but i was unable to quantify it like you could.
