I know that folks have different expectations,  whats harsh to some may be cushy to others..anyway I just put Bilstein HD shocks on an otherwise stock height and stock every thing else on my 91 318is, and harsh is the last word I would use to describe it.  Its smooth,  supple,  tame at slow speeds and still delivers the goods under pressure..they are, imho, an excellant choice for a stock suspension.   The car did have the gas Boges all around and while they were ok, they did not last.  Bilsteins rep is they last the life of your car-that remains to be seen, but 3 weeks in they are great.
