Like Rick V, I was (am?) a Mopar lover. Here are a few quick and easy things to address your issues.

On all of the cars we modded/hot-rodded, the first thing to do was a brake upgrade. My father and I were doing this before the availability of so much aftermarket stuff, so it should be dead simple now. So, ditch the 14 & 15 inch rims. Step up to 16s so you can stuff a decent sized rotor behind them. Use either big single piston calipers, or preferably dual piston calipers. I understand that you can now buy disc conversions for the rear of the old Mopars now.

Along with this mod, stiffen the spring rate some. On a Mopar, this is done by changing out the torsion bars. Use good shocks. Box in the lower control arm for strength. Make sure all of the suspension rubbers are good. Changing to polyurethane bushings adds stiffness and a noisy ride.

Tie the front clip to the rear clip for body rigidity.
