No they were 18's and it was on FK Springs, but I think Eibach would have looked just as good but been slightly less harsh.
I bought and sold the car (my first Zed) with these wheels on and to be honest, I didn't realise how lucky I was, or the value of them. It was only after people started to comment on them that I discovered they weren't standard Zed wheels !
If I had a standard 2.5 or 3.0 Zed again, I'd be on the look out for a pair instantly , but I dont think I could justify changing them onto an Alpina or //M. They come on the 1 Series M Sports too, I think
