The streets in my area suck as far as dips, bumps and uneven surfaces go, and I had the same problems until I installed 1.03 torsion bars and single chamber shocks.
The bars themselves helped to get the front end up a little more as well as not compressing so easily, and the shocks helped with front end dive.
Still I make an effort to avoid speed bumps if I can, and If I do have to deal with them I ease the front end down off of them to limit the compression of the suspension.
The guy in the SUV behind me can just wait.:D
