second, I think that kit is a Zender headlamp kit, it used Hellla Quartz square H4/H1 lamps way back in the day.
USA E30s did get round usa spec ellipsoids for two years but stopped because of replacement costs to owners.
the "smiley" ellipsoids are euro spec. cut-out is to let scattered light lost in the reflector out.
that original e30 looks like it has an ACS front lip spoiler. also the headlamp eyelids with that quad square headlamp conversion
