You're probably on the wrong forum to get feedback on tube bumper designs and exocages. For the most part, this crowd seems to prefer well-executed plate bumpers. (Not insinuating your bumpers aren't well-executed).
Right about the exo-cages, I dunno, they really won't protect the vehicle in a roll over,
body panels are still gonna get crushed, most likely the cage will fail in a crash....roll cages belong on the inside. They loose a heck of a lot strength
on the outside...no cross braces with most exo-cages...more for looks than anything.
If you're gonna cage a vehicle, at least do it right...it might save a life.
Actually I prefer Prerunner style myself....plate is too damn heavy.
I don't really care for the FJ though (Toyota really missed the boat on that fugly thing)...but here is long travel one.
