What are you using for material? So far I stiffened it up a LOT. The end is 1/8" oak ply and the center behind the bumper area is 1/4" oak ply with gorilla glue. I mounted it better to the chassis with thicker steel used for house framing....
In the shot above it was still 1/8" all around without anything substancial bracing...
What LCA and RLCA are you using especially for roll center correction?
