You don't need a lift. If you have any rubbing issues it is going to be with the frame horns or the fender lining. A lift won't help.. you still have to articulate up into the wheel wells and have things work! IMO it is harder on your IFS to run lifted all the time anyway. harder on the CVs, harder on the air struts.
If you must do it for the look, that is one thing, but also consider the stress on the parts. Also, if you really are off roading in a serious way and need the size.. you also are screwed if you have a bad EAS fault or air failure and get stuck on your bump stops.
If anything, adding a lift may only exacerbate these rubbing problems as, due to the physics of an independent suspension, lifting the LR4 brings the wheels closer to the frame.
