E46 sport touring shocks - what to replace with?

[gareth]

My daily bus is currently a rather handsome E46 330i sport touring. Recently it's been getting very twitchy at the rear, especially on wet manhole covers. On or off power too, so I suspect shocks.

What is good to go for on these shiny new fangled beasties?

I have Eibach springs to go on already but these are only about the same drop as the sport springs.

Are OEM Sachs? And are GSF/ECP ones the sport spec?
Or should I just be done with it and get a set of Bilstein B4's for £250?

Heeeeelp!

GSF ones are good I put a set on my sport cab e46 and it made a hell of a difference

Ta What manufacturer were they?

I can tell u the B6 dampers ride quite hard, the fronts good but the back becomes firm

Ta. I CBA with choppy ride on this bus, I've got a coilover shot E36 compact for that!

I would go for the B4's old chap
