mopar handling

First off is this for any competitive racing ?

If it's for general improvement. You probably haven't even drove hard enough to take it to the limit of the stock suspension. This is where you got to be honest with yourself. No point of building a g machine if it's never going over .08.

Tires are the most important part generally the wider and stickier the better.
But really for most a decent sized semi performance tire like 225 or so all around and a set of sway bars will vastly improve handling that would be my first step and go from there.
