I'll take a well tuned suspension over an active suspension. I'm going to learn more about the coil over kit mentioned because my shocks are too soft. I'm going to make sure they are operating properly because they are so soft I'm thinking they must be defective. Changing springs won't necessarily deliver what I want which is stiff recoil valving. So the car stays close to the ground even if you go over a rise at high speed. I call it 'buttoned down'. Nothing has ever been as buttoned down as my 1991 Alfa Romeo 164S. That was adaptive suspension. But, when it was on sport, it was STIFF! When it was on comfort, it floated like a caddy. When it was on smart, it was pretty amazing. The difference between comfort and sport in my Stinger is barely perceptible and I don't feel any change in the rear. My plan, make sure it's working properly, and if it is, swap out for coil overs.
