What thickness aluminum are you picking for you belly pan? I'm assuming that you are picking 5052 for the alloy, since sponsors don't like bending 6061.

I'm kind of worried about your front and back rails crumpling under impact. Our 2013 drive base is pretty smashed in, and that was with at least a 2" flange and a bunch of other reinforcement.

I'm torn on the bumper plate strength. It does look a bit small, but your designs have always had flat plates there, and those seem to hold up. Adding in a bend which is perpendicular to the bumper would help enormously. A different design would be a flat plate on the top of the frame with 2 1/2" bends along the edges which are perpendicular to the frame.

Thanks for sharing!
