What are these wheels?

["Stroes, Gustave" <Gustave.Stroes@xxxxxxx>]

Digesters,

I have in my garage four wheels which i recently purchased to use as track
wheels for my 88 M3.  The wheels fit and should work fine, but I would like
to know what type of wheels these are.

They look exactly like the factory e30 m3 wheels.  They are 15" x 7".
However, the offset is 20mm, as opposed to 30mm for the e30 m3 wheels.
Also, although they do say BMW on them, they do not say BBS, like the
factory e30 m3 spare in my trunk.

So what BMW model do these wheels come from?

Possibilities:  325ix, 5,6 or 7 series (the wheels in question are 5 bolt).

Any ideas would be appreciated.
