Bilsten replacement suspension

[TiTony]

I was wondering if anyone has had the Bilsten conversion done on an Avant? My suspension occasionally sits very slightly cockeyed although switching the engine off and back on rights the problem. Apparently this is a rather common fault on standard self levelling suspension. My local garage doesn't seem in favour of the Biltsens although I see a lot of people have it done on their S6 Avants.

Any ideas on benefits/problems with it and also the cost?

Cheers Tony.
