If you ad a 1.25" BL, MCE fenders and remove the rear inner fenders you can clear 33" tires and maintain the factory ride. Here is what my '97 TJ looked like with that set up, all are very easy mods If you run 33x10.5 you can keep the stock wheels. If you decide to run 33s put a spacer(washer) on each side of the steering so you won't rub your 33" tires at full lock. You can find write ups on how to do this.
Surprisingly stock jeeps flex very well. This is when my jeep had stock shocks and stock springs.
Another cheap mod is buy a pair 4" LED lights from Harbor freight, $10 each, and give your jeep some bright tail/brake lights. The pluses of LED brake lights is you'll never need to buy another brake light bulb and they are super bright! You will need to pick up a new flasher($20) so your blinkers aren't super fast.
My jeep is on the left my friends is on the right(4" lift on right) mine sits stock height.
