Good grief.
If you like the ride height where it's at, you have one choice to do this correctly - buy significantly larger torsion bars. You could also buy 2" drop spindles if you insist on keeping the inadequate torsion bars, but you'd just be trading one set of problems for another.
With /6 bars you will need every bit of that bump stop, because you will be constantly using it. Even at factory ride height you'd be using it, and you're much lower than that. Removing the bump stop to gain back travel is a terrible idea in this case, because you still won't have nearly enough travel to keep the LCA from bottoming out on the frame. Running without bump stops is never really a good idea, but with substantially less travel available than what the car will use with those torsion bars it's a really poor decision for this application.
