I am not sure I know what your idea of full flex is????A 2.5 with bumpstop extensions, brake line drops, proper length shocks and sway bar end links will ride great and clear 35's all day long even at full stuff.
If you are planning on running stock wheels you will need wheel spacers to prevent your tires from rubbing.
The pic is a teraflex 2.5 w/shocks and rugged ridge wheel spacers. The tires are 315/70r17's which run between 34-35" tall for most brands. These are 34.5 (which is also the height that most 35's run)
Lift will only keep you tires from rubbing your fenders and thats only if you use the proper bumpstop. You will still need spacers or aftermarket wheels that will give you around 4.5" BS.Plan is to lift my JKUS and put on 35's. I'm guessing the 3" or 3.5" is enough...I don't want to trim fenders at all, but I don't want rubbing.
Thinking either the AEV 3.5" lift or the Terraflex 3". Would either work?

My best friend and wheeling buddy has a JKRU with 3.5 RE SA lift on 35's and has almost ripped his fenders off 3 or 4 times at flex.
If you are just mall crawling than a 2.5 should be fine, but anything else you will need at least 3.5 or change/trim fenders like my buddy is going to do. The SA lift you can do in the drive way all bolt on.......they even have bolt on LA lifts now for the JK....no more welding!!!!
Sorry, I have to edit my good plan comment with this, with a 15" wheel you run the chance (and a pretty good one at that, of the inside of your rim rubbing the caliper, I would look into a 16 or larger wheel/tire.Maybe, maybe not. My serious offroad rig was an FJ40 and with that I did not have to worry about relocating axles fore and aft. I did cut out the rear fenders once I went spring-over-axle.
The finer points of lifting a Jeep are still murky for me. Apparently I need to gusset my D30 as well. That's really not going to be easy here in Korea (I'm here working). Sure we have welders, but getting the message across... (???)
Anyway, I don't intend to do any hardcore stuff, but don't want to damage my Jeep if the suspension is compressed, either.
I'm aware of the backspace issue.
So, for now my plan is 2.5" AEV lift, properly backspaced 15"x8" wheels (Discount Tire recommendations), and 35x12.5 BFG A/Ts. I'll probably beat the pinch weld in at the back (heavy plastic hammer) as someone else did, I like that idea better than cutting it. Oh, and get the front end gussetted. sigh...that was unexpected and BS...
A 15" alloy wheel with 4.5" of backspacing or less will work fine. Discount Tire knows which wheels will work. I got my setup from DT and I love it. 15x8 Level 8 Trackers (3.75" BS) with 35x12.50x15 KM2s. Lift is the 2.5" AEV DualSport with geo correction brackets. I have no rubbing but do intend to trim my pinch seams at some point.Sorry, I have to edit my good plan comment with this, with a 15" wheel you run the chance (and a pretty good one at that, of the inside of your rim rubbing the caliper, I would look into a 16 or larger wheel/tire.
