E30 Stance - Steel wheels or modern wheels??

E30 wheels is a magnificent topic of discussion, so lets have a couple of different takes on wheels for the old 3er...

By far the most common wheels to bestride the E30 are cross-wire / BBS styles. and beyond that owners tend to stick to solid period styled alloy wheels like Azev-A five-spokes or Borbet C. Personally I think the old-school BMs look best with steel-wheels such as the almighty Weller competition wheels, as in the pic above, especially with a lowered car. These are built for heavy-duty dirt-track racing and off-road and I think give a lowered E30 the best squat / rat look.

At the other end of the spectrum, here are some ultra-modern Japanese-style alloys on a 325is. I am not 100% on who makes these, but they look very much like RAYS Volk or Rota wheels. You don't see many wearing rims like these, certainly not done well anyway, but why not? Sharp lines suit sharp lines and the 3-box shape combined with large modern alloys gives the E30 a very purposeful look and go-kart stance.

E28 5er - Interesting unknown rear wing/spoiler... Hartge maybe?

A lovely barn-find shot of an E28 528e in the USA, but on closer inspection it sports a striking rear-wing/spoiler that I have never seen before. Who makes this piece? On first impression I would say one of the period Euro-tuner firms like Zender or Hartge, but after a bit of research I can't find an identical one. The chrome-trim makes it look as if the spoiler was fitted later on though and the car is not a tuner model. Perhaps someone can shed light on this spoiler's origin?

Hartge lay claim to a few E28 aero-parts and a I can find a couple of similar rear-wings, pictured below. The upper one is a rounded type and I am not sure is definitely made by Hartge though the badge suggests it is, and the second pic shows a Hartge developed E28 with their own rear-wing fitted, very similar to the one at the top but not quite as tall and curved on the top-edge not flat. It could well be that it is a similar version of this same spoiler and still made by Hartge, but I cannot find it.
