body stiffening

Sub frame ties are in my book mandatory. They are the single most beneficial add on to these cars. The old Mopars have lived in the shadows and been condemned to the age old thought that they handled like shopping carts. This is IN MY OPINION based on the fact that these cars were drastically under sprung in the attempt to make them comfortable to drive. This is why ties are so important. When you increase spring rates it puts even more force on the unibody. You need to stiffen the chassis in order to make the "springs" do the work. If the spring is stiff but the body twists first then your not achieving much.
