Springs don't

But the Saab 9-5 rear springs, and especially the Aero rear springs, and doubly especially the Aero Wagon rear springs, are incorrectly designed and the springs "take a set", which is to say they deform permanently when the spring is fully compressed. Spring Design 101 includes not doing that. But after taking a set, the spring constant (stiffness) remains the same, with the only detriment to ride and handling being that the suspension bottoms out sooner and the tail drags some. And because the rear suspension is a cheap(er) design, rear camber change with the sag causes excessive tire wear.
Using shims to level the rear suspension would seem to deal with all the issues relating to sagged springs.
