Once you trim the front fenders in that area right in front of the doors you shouldn't rub at all when flexed. You have plenty of space above your tires so if you hit your flares then you need bumpstops. I wish I would have done that to my XJ rather than grinding my tires into the wheel wells all the time. You don't need uptravel like you need downtravel and allowing one side to come up too far will limit the downtravel of the opposite side.
