ABS belly

Julian's belly is a work of art! If he spec'd the thickness that he used, we know it'll hold up at Australian speed limits.
At 80-mph, though, you'd be in a different kettle of fish.
Remember, aerodynamic forces vary as the square of the velocity.
By increasing speed, from, say 55-mph, to 80-mph, aero forces, stresses, and strains will increase by more than twice! Perhaps requiring shorter spans between supports.
