Thanks for the input, everyone.
Over the past couple of days I've ridden in a Z4M and driven an E90 M3 both equipped with KW clubsports. In the street of LA and SD respectively. Both were adjusted somewhere in the middle of the adjustment range and both felt firm but fine on the streets. Actually the E90 similar to my previous E90 equipped on V3s.
So I'm even more confused now *sigh*
