Wheel Identification

[TrailRated]

Can anyone identify these for me? They measure from edge of lip to edge of lip as 16", but are BBS stamped 7Jx15 on the hub. My gut feeling is that they are off of an E30 M3.

You need to take the cap off so I can tell if they are 4 or 5 lug

4 Lug = non-///m E30 15" basket weaves. Et 20

5 Lug - ///m 15" basket weaves. ET 20

It's all in German, but you can figure out most everything. Good info.
