FYI, any 4runner running 33"ers will have rubbing. With just a suspension lift, when fully compressing the front wheels, the tires will rub the top of the inner fenders. Adding a body lift 1"-1.5" will minimize this rubbing (you are moving the body away from the suspension bumpstops). Also 33"s will usually rub the back of the front fender wells when turning. The majority of the time will rub the upper front control arms (sidewall) on stock wheels (stock backspacing).
If you wheel lightly or not at all, the rubbing on top shouldn't be an issue. The rubbing on the back of the front wheel well will not change. You will need to do some trimming and/or pounding. To eliminate the UCA rub, you will need wheel spacers or wheels with less backspacing.
Note: Not all brand/model tires measure the same. They can vary +or- 1". Some tires will rub more than others. (I know someone that is running 33" BFG ATs on stock wheels and just barely clear the UCA)
