I went and look at the wheels and they are 2(3) piece with allen screws and very clean but with talking with this kid(about 23) who collects wheels for Honda's and said I would rather get a staggered set of rims and he said he was some where and he saw 635 alpina going to the junk yard and what caught his eye was the steering wheel and thought he take that and the shift knob because he thought they looked rare.He also took the wheels a staggered set of alpina's! So it looks like I'm going with 16"! I'm hoping he comes though because they are in a barn Northern Calif.? But like I tell my kids it NEVER hurts to ask because if you never ask you'll never know.
PS Doesn't have the wheel anymore but gave the knob for free!
