The wheels are 6J width (6 inches). No problem with arches clearance. I have a set of 8J Ronals that look like Minilites but I don't think they will fit without some mods or lock restrictions.
Hubs from the 410 onward use a larger Point Circle Diameter (PCD) similar to period Jaguars. BMW rims are fractionally smaller at 120 mm PCD but can be adapted.
When changing rims, take care that the taper profile of the nut matches the seat in the wheel. The wrong angle can reduce the contact area and lead to cracking.
Steel rims can be altered to hold the original hub caps and retain appearance.

Thanks, John. I hadn't realized about the nut taper issue. I appreciate that warning.
