Basically my sister is getting the '21 High Altitude edition and when it was parked next to a rubicon she didn't like how hers sat a little bit lower compared to the Rubicon from factory. I was thinking her best option would be a small 1.5"-2" spacer lift. Her jeep will probably be a 95% pavement princess 5% light off-roading... should get just get a spacer lift or a spacer lift with bump stops, or a spacer lift with shock extensions? Any other cheap-is options? She also may or may not get slightly bigger tires than factory size.
