Thanks Guys.

I will give the UK bilstein people a ring and see what they can come up with, as there's nothing listed on their site for the RS.

Must admit, I was abit worried about the dodgy spacer trick, but it seemed like thhe easiest solution. Would prefer Bilsteins, partly for their rep, and partly just to go along with the rears I already have. But if it comes to it I will go for one of the other makes, you've persuaded me

Only problem, is that I want standard height rather than lowered, but we'll see what they have to offer.....
