As others have already suggested, rubber bushings.

That said, just how bad does it need shocks? If the whole body waddles and rolls when you start giving it the beans on one corner, the shocks can be contributing to your wobbly behavior. Unlike most cars, when you go pushing hard on one corner, you shouldn't have any bouncing in a Benz. If you get jiggling, or a rebound or two, shocks are definitely on the list.
