lift and backspacing questions

I am getting ready to purchase some Incubus rims. The off road edition. They are a 17 x 9. First question....I am wanting to start out with a 33" tire, so can I run with the stock suspension or will it need to be lifted first? Second....I do not totally understand backspacing. Will I need spacers, or not? I like the tires to stick out somewhat from the flares, but I dont want it to look like a tonka truck either. I am on a somewhat limited budget and have been looking at the skyjacker 3.5" standard lift kit with rear track bar brace. Will this be sufficient or is there a better set up? I have never installed a lift kit before, but I am proficient in the garage, so it won't be a problem on the install. From what I have read and the videos I have seen, it should be rather easy. Thanks for the help! Oh yea, I drive a 2011 2 dr sport

1..You will not need a lift for 33 however you will need the correct bs so you will not rub in full turn or articulation.
The wheels that you are getting what is the back spacing?
You do not need wheel spacers if you have the correct bs. If the wheels you want have 3.5 to 4.75 of bs they will work.
not sure with skyjackers lift but with other 3.5 you can run up to 37 or larger.

Stay away from skyjacker. For 33" tires look at a Year Flex budget boost lift which can be done for around 250 bucks. If you want to get into a spring lift look at the Rock Krawler 1.5" lift. With 3.5" of lift you can do 35" easily. As far as backspacing you would be safe with 4.5".

The wheels have a -12 offset?? If I go with 35's, will I not have to change gear ratios?

Ok, I did some reading through the forums and seen that a -12 offset is equal to a 4.5 bs so that puts me in the ballpark. Now, if I do lift 3.5" and go with 35's, will I not have to change gear ratios? I have the 6 spd trans.

Depends on gear ratio. If you had a rubicon and 4:10s you would be Ok, but if you have 3:73s - 3:21s you will prob want to re gear.

You don't want a 3.5" lift to run 33" tires, not from anybody.

Some build info here:

I went with a 3.5" lift and 35's on 17x9 with a 4.5" backspace as my initial setup. It was a perfect street/trail combo. Stock 4.10 gearing with a manual transmission. I wish my 4-wheel-low crawl was slower, but other than that it works great.

I later went to a wider stance with 3.5" backspacing because that was the only size the rims I wanted came in.

I personally wouldn't spend the coin on a 3.5" lift just to run 35s. my wife is running 35s with just a 2" rough country coil spacer lift and they fit great. now granted, she is not using it for hardcore wheelin so running is a non-issue.

I could see a little more lift benefitting you if you are wheelin it hard.

our jkur has 4.10s and while it's fine around town, it does want to downshift all the time when out on the hwy. we won't be regearing anytime soon since it's just a fun toy for her and our 3rd vehicle.
