I have the Rock Hard Sport Cage but I am thinking of running the front and rear seat harness bars. I like the idea of putting in 5 point harness's as well as the added strength. I know they only tie into the pillars with three screws on each side(at least that's what it looks like). I am looking for some feedback from those who are running them? Do they take up much room? Is the front a safety issue for those who are in the back seat? Do they really add to the strength in the event of a rollover? Are they just a wast of money? I wonder if in a flop, would they give much strength to hold things together? Thanks in advance.
