That looks great!! I wasn't sure what to call the lift I will be doing to my JK.
I'm going from my 13/55's to a set of 18/59's taken off a friend's Rubi Unlimited, as well as the Rubi shocks, and a TF leveling kit. Is that a frankenlift?
I'm estimating about 2 inches lift up front from the springs, plus adding just one spacer will get me to 3 inches higher. (Adding the second spacer would get me to 4 inches...too high). For the rear, I'm estimating about 1.5 inches lift from the springs, plus adding the spacer will get me to 2.5 inches higher.
If I do both front spacers that would give me at minimum 3.25" in the front (or even as as much as 4"). That's 1.25" more than what I'm getting out of the rears. I think it makes more sense to just use one front spacer.
