Question Advice on my budget boost plans please

I need some input on my plans for a budget boost. I have a 2013 wrangler 2dr sport that I want to lift approx 2.5" to 3". I'm currently thinking about using the following:
1) Unlimited Rubicon take-off springs (because of the added weight of bumpers and winch Iíve added).
2) 2.5" Rubicon Express budget boost with shocks spacers and bump stops.
3) Teraflex 2"-6" sway bar quick disconnects.
Can the more experienced among you offer and helpful advice as to the pros and cons of this setup? I'm obviously on a budget so telling me I should get the latest setup from Teraflex or BDS would not be helpful. Also I am not just going for looks. Off road performance is important (although I'm not planning on doing any 10/10 rock crawling).
Iím running 33Ēs
Thanks for your help in advance.

Should I take the lack of comments to mean this is a good idea?

I'm running similar set up 2" BB and 17/58 springs from a JKU. Your axles will be off center 1/4"-1/2" depending on how much lift you get. I had just been running the front springs for a while and added the rear in the past year and since adding them have had rear driveline vibes so this spring I will be adding adjustable control arms to correct my pinion angles. Depending on how much down travel you have you may need to add brake line relocation brackets or longer brake lines, I am running longer travel shocks so needed them.

I do not have any complaints with the off road performance, I'm also on 33's.

I figured I'd need longer break lines but didn't realize a lift would put my axles off center. Why is that and does it cause any problems? The stiffer rear springs are the cause of the driveline vibrations? You'll have to bear with me, i'm new to the apparent art that is lifting a rig. Thanks for your help and nice rig btw.

With a fixed length stock track bar when you lift the suspension the track bar pulls the axles to one side, this can be corrected getting adjustable track bars or correction brackets.

The added lift is the cause of the driveline vibration, with the short wheelbase it puts the rear drive shaft at a steep angle that can result in vibrations. The vibes were not that bad with the stock drive shaft but the added angle caused the joints to wear out, I replaced with an aftermarket double cardan ujoint driveshaft and I feel the vibration.

Can you recomend a brand and model number for the track bars and drive shaft? is there any way to mitigate the vibrations?

also did you get an alignment done after your lift? That could contribute to the vibration couldn't it?

So after more research it seems like driveshaft replacement is a common byproduct of lifting a wrangler... things are becoming less and less "budget" in my boost plans.

Ok so to update I have my Rubicon Unlimited springs on and they gave me about 1.25" all the way around even with heavy bumpers (70+- lbs) front and back. My new plan is to add a 1" spacer in the front and a .75" in the back. I'll also add shocks designed for a 2" lift and DIY brake line brackets. The ride on the new springs is slightly stiffer but barely noticed.
