Thinking of switching from H&R springs to Eibach.

[nomis36]

I'm thinking of doing the switch because my mrs. keeps moaning the ride is too hard! It is a bit on the firm side to be fair but the handling is amazing on decent roads.
Anyway, in the interests of keeping the piece i've said i'll look into softening it up a bit. Has anybody tried the pro kit back to back with H&R's? I've done some googling on it and it does seem Eibachs are a bit softer than H&R's, is this so or am i better going back to stock m sport springs? I threw my old ones out as they were very crusty and old.
The shocks are bilstein b6's by the way.

Oh yeah, and if anybody has got a set of decent, i.e newish Eibachs or stock m sport springs for a 6 pot e92 lying around and want to 'throw' them my way you're welcome to by all means

I'm quite sure this is in no-way helpful to you - but FYI i ran Eibach pros on my old m135i for about 4 years and thought they were superb and OEM ride quality (better in fact)
