The shocks can't control the bounce when all the tension is off the torsion bars. Jack it back up to normal ride height and put the right wheels back on, and your bottoming-out problem will go away. Otherwise, buy a trailer, and tow your lowrider to a car show, win your trophy, and trailer it home. It's dangerous to drive when it's bouncing all over the road.
