I put lowered Kilen springs and Bilstein touring shocks on a 945 a few years ago - it was a much harder ride than standard. Obviously the handling was vastly improved, but the addition of ipd anti-roll bars was probably the main reason for that, not the spring/damper combo. On motorways it was fine, but it was quite crashy on potholed A and B roads.

I replaced the rear suspension of my 850R about 2 years ago now - this time I went with the OEM stuff and fitted new Nivomats. Expensive yes, but it retained the ride quality in what is after all a family road car, not a track car. IMHO keeping it standard is best - but add those ipd anti-roll bars if you want to sharpen up the bendy bits, they DID made a big difference without making the ride harsh.

I'm about to refresh the suspension on my current 940, this time I have some lesjofors lowering springs and KYB dampers. The dampers are standard spec, which I'll be fitting with the existing original springs first to see how it goes - afterall new dampers will beat old worn dampers every time and the result might make the car as good as new again. I'm undecided about the lowering springs this time - as I said, the antiroll bars made the biggest difference to the handling.
