I don't know where you got stuck on the rollover thing. The dynamic rating is so low on Jeeps and Broncos because the tops are plastic and too much weight shifting around up there on the stock rack can potentially literally rip the rack out of the top or take the entire cap off its mount. Yes, there is an increased rollover risk any time you mount anything up higher raising the center of gravity. That's true whether the roof is plastic, steel or adamantium. But it's not why Jeeps and Broncos need more reinforcement if you do choose to mount something up there.No matter where you distribute the reinforcement, it's still 110lbs on top of the vehicle. It's not gonna make it less prone to rolling no matter where you tie into.... Roof or bumpers... You're not shifting the CG at all.
