Vehicle is 52 plate 3.2 Elite Estate with 60K on the clock.
Offside wishbone subframe bush is showing signs of splitting and offside front tyre is just starting to feather on inside edge to confirm it so I know both wishbones will need changing soon. While I've got it apart I am going to change the front struts/springs as I can't be ar$ed to do it again at a later date. My original elite front struts are not leaking but are quite bouncy.
Due to OOF's varying opinions I am opting to re-bush my GM wishbones subframe bushes with GM parts and poly the front bush. I'll also give poly donuts a trial on the rear.
The question is, do I buy new MV6 front struts and springs or go for Bilstein B4's/Eibach springs, bearing in mind that I have only just fitted brand new rear SL dampers. Will it look odd with MV6/Bilstein front dampers with elite SL dampers on the rear or should I just keep my elite springs to maintain correct height?
As the rear dampers are brand new I'm pretty much stuck with them and they are handy when towing but I would like the car stiffened up a bit. Will MV6 front & elite SL rears cause any issues? WIM is not far from me so set-up would be done there.
Any comments/suggestions welcomed.

Alan
