I doubt that there's any single compromise for requirements as disparate as those most likely are (been there). Adjustable shocks & struts are going to be your best bet, as harshness is much more a consequence of shock damping than spring rate.I don't drive my GT PP every day but I bring it out on weekends and do 2 to 3 track days a year. I'm just trying to find that impossible compromise between fun on the track and keeping my wife from complaining about a harsh ride.
To find your settings for the track, follow Koni's tuning procedure (whether you have Konis or somebody else's, and whether single or double adjustable). To suit her, you'll want to let the suspension - maybe the rear suspension in particular - move enough to clearly notice but still settle without noticeably bouncing a second time. It'll definitely feel 'soft' and underdamped compared to your track setting.
Too much rebound damping could cause the car to come back down harder by not letting the axle drop back down as easily, making the second impact worse than need be. This could be mistaken for excessive bump damping. There are other effects (hysteresis and crosstalk between bump and rebound damping) that also affect how much bump damping force gets developed.
