I had (almost) those on my '94 E36, and could not get rid of them fast enough. They were very difficult to keep clean.

I replaced them with a set of Style 22, and mounted them with 225/45x17 tires.
One thing to think about (be aware of) is that the 5 and 7 Series cars have a different diameter center bore than the hub on the 3 Series.
The 5 and 7 cars have a 72 mm center bore, but the 3 Series has a 68 mm hub, so you will need a shim (hub-centric ring) that fills the space between the hub and the bore else the wheel can be mounted off center and this will give a symptom that mirrors a poorly balanced tire.
You could mitigate the center bore diameter issue by putting the lug bolts in loosely until all are in, then going finger tight so that the tapered shoulder on the bolt just begins to make contact with the hole on the wheel, then shaking the wheel so all bolts and holes are centered before tightening the bolts all of the way. -> EXCEPT BMWs are hub-centric not lug centric.
