or rather bouncing down on the tire lol

 

My point is if you want to carry people in your back seat, GET 4 DOORS! We have 4 vehicles, all 2 doors. The Z71 is NOT an extended cab. The '82 Olds Regency is a tank, but a 2 door coupe, and the new Solstice GXP has ONLY 2 seats. Get a mini-van, or an SUV!
If you are having problems bottoming out with no passengers, then put in new springs, as the old ones might be wore out. Spring rubbers are a band-aid fix.
