You have a lot of questions. While they are covered extensively in older posts let me see if I can help in one post:
Considering the COMFORT of ride ONLY....which one of these lifts is better?
I do not offroad and the only offroading I may ever do would be trails to get to a hunting or fishing camp and of course New Orleans' pothole infested streets. I simply want more ground clearance so I can put some 275 60R20 Michelin LTX A/T2s on my 4runner.
Which will give me a better ride? and if the Bilsteins...HOW much better?
So you don't off road at all.
I'm trying to get more sidewall and a slightly more aggressive stance with minimal decrease in MPG.
275 55R20s sidewall height increase is negligible.
You want a mall crawler. Check.
I was considering the Daystar Comfortride spacer lift. Do I only need to lift/level the front for the tires to fit?
With a lift or level your tires WILL rub. Without a lift or level your tires WILL rub. See, even though tires are a specific size, that size is nominal. Your new tires could be bigger, or smaller, than the nominal dimensions hence the chance of rubbing either way. The parts that rub will get lifted but unfortunately not out of the way. Now if you go with aftermarket wheels with a different BS then all bets are off and they still will rub.
I'm limited on what I CAN do. My parking garage is only 6.5' and I'm getting a rack from drabbits.
I would like to get some beefier springs in the back though for towing my boat. Except all the ones I have seen with more load capacity raise my rear end at least 2"
Suggestions?
Airbags for the rear to keep from sagging would be my suggestion.
If you want a lift for looks, and it sounds like you do, then go the spacer route. Its cheap and you get to keep a $2K OEM suspension system. Why? You don't go off road so you do not NEED anything else. The bigger tires WILL rub, depending on many things. My advice here would be go get your spacer lift, go get your tires and then modify as necessary. Oh, those "many things that WILL cause your tires to rub a lot worse?
1. Factory caster setting
2. New tire actual outside diameter
3. New wheel offset
4. Actual location of inner fender liner. (they could differ from vehicle to vehicle by a bit)
Take a look at the tire fitment guide in my signature. You will rub... a lot. You will possibly have to do a body mount chop, remove mudflaps, trim behind them, move the fender liner forward, trim the front cover. You might have to get aftermarket UCA's to adjust your caster higher.
Now, you might not have to do all these things but I can guarantee you will have to do some of them. Even a 3" lift won't keep you from having to do some of these things. Hope this helps and good luck. Oh, you will probably need to run a wider rim judging from the section width of 33's.
One more thing: Your gas mileage will take a hit. Tires are much larger diameter and much heavier. How much of a hit depends on how much city versus highway driving you do. More city = worse gas mileage. Your acceleration will suffer as well. Many running that size actually re gear.
