| Because I am not intimately familiar with the Z32 chassis, I reserve my opinion of the overall post, but this section confuses me: Folks may be experiencing less harshness and vibration, but the foam, in order to work, (this comes from a structural engineer, folks) must be as strong or STRONGER than the skin it's in (in this case, layers of 18-guage sheet steel), in order for the two components to make a sandwich that is stronger than either of them alone. IT's not going to happen. From my professional experience (engineering structural fiberglass and carbon fiber sandwich panels) I don't agree that the foam has to be as strong or stronger than the skin it's in. Why would you even bother using the skin? The foam isn't a load-bearing component of the system. It only serves to hold the skin components in place, which is important when buckling is a possibility, such as in compression, torsion and bending (which is essentially a tension-compression system).
