@jamesroney was looking at my Bronco the other day and mentioned this same/same scenario. I’m not there yet, but getting there and he gave me some good stuff to think about regarding this.
My original plan was to mount my seats to the cage, as well as my 4 point harnesses. As the years have flown by with my project sitting, I “sprouted” a wife and two kids, have matured (only slightly), and tastes have changed (no more racing pesetas either) and I have to think of what will help my wife want to ride in my “true first love” before her, I’m pretty sure that the cage mounted seats wouldn’t have helped and so at the urging of Cage Dave (and I agreed) I did away with it (or he did for me).
Someone above mentioned that their cage is tied to their frame…I think that’s the key here. My cage is tied to my body and so what if my seats are too, no? I think if my plan was going to include some serious crawling and above average risk of rollover, then cage to frame as well as belts is a “duh” non discussion.
For me, the cage is there in case I roll to protect the fam as there is nothing up top even if I do out the flimsy sheet metal roof on, which is nothing.
Not arguing that tying to the cage isn’t better, it is, but just is it needed in a mostly street application is more my question.
I don’t want to end up like
