Help me prove OEM Vs DOM .090 / .125 Cage strength

So… Fiance and I have a RZR, we are both really loving it, doing a little bit of trails, duning, Rock crawling and a little bit of everything.

I have had it on its side from rolling once, on its top once, then rolled back to side once rock crawling, then this weekend was doing the video below… So I want to beef up my ride and install and aftermarket cage, seems like a logical move right? Well, I’m having an issue getting her to believe that an aftermarket cage is stronger than a bolted together, thin walled, creaky OEM one.

We are both engineers… so data / numbers FEA analysis … something to help me prove to her that stock is weaker than a well made aftermarket cage, would be extremely helpful. I think she believes the welds are going to be the weak point. . . which a poorly welded one, yeah maybe, but some of the welds that are the rzr from the factory are a joke, and they hold :rolleyes:

So, if someone has something … I really would appreciate the help!
thanks
