Probably be a pretty rough ride without springs. Short springs usually give you a rough ride as well.

You could always do like everyone else and throw some air bags in place of the springs, then you could set the crossmember 2" off the ground when you park, and bring it up to a reasonable height when you want to actually drive it. The air bags would give you a soft ride as well.

I don't trust air bags, but that might just be my paranoia showing.. Gene
