Thank you.
If this were a 2 door, I'd be inclined to make it a corner carver like the Green Brick.
Being a 4 door means that I'll feel just fine building it more tame with less emphasis on performance and more on reliability and road-trip worthiness.
I do plan to leave the stock springs and torsion bars but to add better shocks and sway bars.
This is one of those times where KYBs are not 100% horrible. They tend to shore up a soft suspension a bit. I have a set that I'll try. If they are too stiff as they often are, I'll just change them out, no money spent or lost.
