PM sent
In case, others are interested, here is the PM I sent.
They're from Savini, the Model is BM13 brushed silver in 22". They don't really save much weight but are not very expensive either. Only drawback is they need attention when cleaning. I didn't think about that and now, I am spending about 5 min per wheel! They also stick out from the tire a bit, so you'll have to be careful when parking
