Joe, Just curious why no 4 link in the rear? I ask because I'm sure you have a good answer!;D
I love a good 4 link, but I don't need it on this rig. My design idea was to make the most capable rig I can, that I can drive all over, including long trips on the street, yet still retain excellent street manners. I still have the buggy for the extreme stuff, but I wanted to be able to drive this to SOB (1400+ miles), wheel it around and drive it back home, all in relative comfort.
My personal opinion: until you decide that your "normal" wheeling requires you to minimize the body panels, you might as well stick with leaf springs in the back. By making these 6" longer than stock they should allow great flex and a nice ride.
