2009 3.0i E89 Z4 rear shocks

[flybobbie]

Nothing to replace, reuse.
I have fitted Bilstein B4, not much difference other than cost from B6 i had fitted.
I was looking for a slightly less rigid ride, as my daily drive is country lanes and fed up of being bashed around, the old bones can't take it any more!
Interesting the B6 had done about 45k and the two rears had developed different response rate, perhaps the gutter side got more wear.
If you replace fronts it's worth while replacing the upper mount ball bearings, one of my cars was worn.
Often gets ignored.
