"Flighty" = FR adj. LCA's
Ever since I had my TF Leveling Kit installed I have experienced some issues w/ "flighty" driving on the road. I've played w/ my tire pressure and 32psi seems to help a little but it's not the cure all. So, I'm thinking of installing the JKS or TF adj. LCA's to help me out. Can anyone give me some advice concerning this issue? I'm assuming the caster is off. Will I also need to install the same in the rear? I do plan on installing the adj. FR track-bar as well for future mods. So far I'm putting together an order of TrueTrac's FR/RR, TF FR Knuckle Gusset Kit, and 285/70R-17 Duratrac's. (Don't plan on going any bigger, keeping mostly stock since I travel extensively and want to keep mostly stock ride mpg's for time being).

honestly, i thought my JK's were flightly right from the factory. and, adding a lift to them only aggrivated the feeling. installing a set of adjustable front lower control arms will help you to add a bit more caster and that will help fix the flightlyness you are feeling. you only need to do this up front and this write-up will be able to help you out:

I had an 07 and my wife also has a JK, and other than the usual cardboard box in a windstorm feeling, I can definitely tell there is much more attention needed with paws on 10 & 2 almost always.

WOL is right about the front lower adjustables to adjust caster.
Given that all you are running is a TF 1.5" leveling kit, before you drop the $330 on new front lower arms, try using WOL's write-up thread on alignments (linked above) to toe-in 1/16"-1/8" and lowering your air pressure to 28-30 psi. This will help. The question will be if it is enough for your preferences.
With a leveling kit, you don't really need adjustable trackbars or adjustable rear control arms.
With 33s and a leveling kit, you don't really need C gussets.
If you are paying to add TrueTracs front and rear with your 6 speed, I'd use it as an excuse to upgrade to 4.10 or 4.56 gears if you plan on staying with 33s. The labor cost would be the same as a regear.
