You'll need a better description than "best handling streetable" before you can get very far. Both handling and streetable behavior are very subjective.

If you are looking for advice I'd say you should start by riding in some modified cars and finding the compromise between handling and comfort that you like. It is very easy to turn a mushy factory Mopar into a dump truck by installing big torsion bars and cheap shocks. If you don't like mushy and you don't want to drive a dump truck then you'll need to find something that works for you.

Hotchkis has a complete handling package that takes the guess work out of the equation so that is one place to start. Otherwise just do what everyone else does - experiment. Try a few different sizes of bars and see what you like. Try a few different brands of shocks to see which one feels the best to you.
