my e90 went from a set of sports suspension springs to Eibach Pro-Kit. To me, they're not bouncy but provide a pretty good handling and ride quality.
i'm used to stiffer suspensions so for some, sports suspension may have be a little harsh for some.
anyway, it didn't really seem the Pro-Kit's drop was too different from sports suspension but i've got just the right amount of wheel gap so i'm not tucked but not rollin' like a 4x4.
