Not to burst your bubble, if your shock mounts are bolted to the body of the car then you really need to keep an eye on the mounting points on a regular interval. IF you run really stiff shocks they will act as a lever and work the body and eventually will tear the metal apart, kind of like bending a coat hanger back and forth, the metal with fatigue and start cracking, unless you have managed to bolt them to the frame member thru the boot deck?
