They are bbs sv wheels, but they only come in 20". I'd have them if they came in 18" size.
I have seen similar on a German website(in 18") when I was looking for alloys last year. Only reason for not getting them was my rivas came up cheap (and virtually new)
When I looked last year I couldn't see a 19" option. I assume they'll be the same weight rating as the 20s.
If I had spare money I'd be ordering a set myself
