Alright so here is the deal:
I currently have a 3" Zone kit on my 2DR 6spd X.
What I am installing in the coming month (ie before wheeling season here) is:
- Currie front brake lines
- Currie adjustable front lower and rear upper control arms
- Currie adjustable front trac-bar
- Tom Woods rear driveshaft
- Spacers
What I wish to know is:
With a front stinger bumper and rear tire carrier what size spacers should I run to level the JK out at approx 3.5" of lift?
What length should I set my front lower and rear upper arms at for optimal performance?
What length should my front adjustable trac bar be set?
Anything I am missing?

 

a set of 3/4" spacers should bring you back up to where you were/want to be.

the fronts should be set to about 23" eye to eye.
the rears will need to be set to whatever brings your drive shaft and pinion in line with each other.

this write-up should help you out:
