A 4" is good with 33s to 35s. 32s will be good with a 2.5" lift. Skyjacker use to be very good but I hear alot of guys talking them down now. The lift for 539.99 sounds good. I dont know anything about the sport and economy tho. Also from other guys talking and my own experience I would do a 4". Once you lift it you will get use to it and prob goto a 4" anyways. But its your jeep I dont know how you plan to use it. Ether way it will look good.
If its worth doing its worth over doing
