Accepted wisdom with older Saabs (V4s and 99s) was always to go for uprated shocks first, and then go for uprated springs if you wanted more. The principle worked pretty well. As an example, a bbbbbog-standard 99 with turbo Bilsteins made a very good handling car without losing too much comfort. My V4 with S&R forest-spec springs and Bilsteins was bouncy enough on the road (though most of the travel was tyre deformation), it would have been hell with a lesser damper. I kow different cars will respond to different tweaks but this seems to be a general principle that works.
I'm frequently surprised how many people with the newer cars tend to go the other way round, as to me it doesn't make sense. Standard shocks are designed for damping slower frequency, longer amplitude oscillations (sp?) than you're likely to get with a shorter, stiffer spring. Which probably explains the problems people have with Eibach springs becoming very bouncy on standard shocks. My 9-5 on standard suspension would definitely benefit from better damping but I could probably live with the current spring rates, if I could be bothered to do owt to it that is...
