What height did you set the bottom of your frame rail at?
I'm not positive where it will end up, as I used stock TJ rear coils in the rear, but I set the front up to have the belly 19" off the ground, + my 1.5" crossmember.
As it sets, if I set the front with 5" uptravel, the rear is 1" tall UNSPRUNG. I feel I will end up using 4" lift springs or 2" spacers in the rear.
Low is cool, and what I was shooting for, but once I stepped to a 40 from a 37, I cant get it as low as I wanted without cutting the rear wheelwell into the tub.... something I dont want to do on this one. Time will tell- I have the trans and tcase sitting in it now and once I mount the engine I'll drop the tub on and see where I'm at. Wheelbase is sitting at an even 100", with an inch left to push it back, and just tacked bungs to pull it in to center the rear in the streched corners.
