Setting your caster is a personal preference/opinion, of course, but at 4 inches, I'd imagine you will find very few posts from people who are happy with the handling. 
Q: What is Caster? How much do I need?
A: Caster is the angle upon which your front axle sits at in order to help keep your Jeep driving straight. Positive caster, which is what you want, will cause your axle to sit in a way that your pinion shaft will be dipping ever so slightly towards the ground. Too little or even negative caster angle can cause your Jeep to wander and feel 'flighty' or 'darty' as I've heard some people call it. From the factory, your JK will have +4.2° of caster and if you lift it and install larger tires, you will need to increase this amount to help compensate for the modifications. At 3"-4" of lift, I have found that +6°~8° of caster will do wonders to help improve the handling of your Jeep JK Wrangler.

Looks like he was playing in some mud puddles. I've seen a lot of guys turn their ram air intake backwards when they know they are going to be splashing around.

I just installed the TF 2.5 lift on my X last week and found the steering to be flighty on narrow uneven roads. Uncomfortably so. Therefore I am expecting my new flexible lower front control arms today. I do have a winch and bumper combo up there that weigh's 190 lbs. too.

That looks really high for a 2.5" lift, is that normal with the TF 2.5" coil kit? I didn't notice it as much before seeing this post. I understand that they do typically lift a little higher, but that just looks a lot higher.
