Best bang for buck to improve handling?




I bought this car over a X5 or Cayenne really because I know the drivetrain is solid (mine is a late 08, almost 09 so no balance shaft issues) and these ML's seem far more reliable.
However the handling sucks. The ML is a true truck unlike the X5 or Cayenne.
Still, I think I'd like to improve handling just a bit so it doesn't feel like it wants to tip over. I think even sacrificing an inch or 2 of ground clearance would be a trade off I am willing to make as that should still be high enough to clear basic off road obstacles.
What is the best bang/for/buck suspension setup when it comes to shocks and springs?
What about swaybar upgrades? Can I drastically reduce roll with a set of used W164 Ml63 swaybars?
