Agreed 100%. . There is a measurement for street use. It is reached by getting the ground height difference between the lower bushing pin and the ball joint. If you want it lower do what ever you like. Its your suspension and tires
There's a right way to do this though. The factory spec means all of about zilch once you run bigger torsion bars, which reduces the amount of suspension travel. Lowering the car to the bumps with stock torsion bars will definitely give a crappy ride and handling, but lowering it and adding bigger torsion bars is no big deal, it will improve ride and handling if done right.
I run the dome shaped poly bumpstops and 1" or bigger bars. My Duster will soon be wearing a pair of 1.12" firm feel bars, and I plan on around 1" to 1.5" of travel to the top of the domed poly bumpstop, will depend on how it sits with the 275/35/18's up front. With a 300 lb/in wheel rate I suspect that will be more than enough to keep me from ever contacting them.
