Now that the flat is nearing completion, you are building an all aluminium bodied 2 11 right?

I would guess 1.5mm NS4 alloy (or 16 gauge). That is the spec for some kit car aluminium panels (eg Ultima), Lotus undertray appears to be made of something pretty similar.

Mind you the spec says good corrosion resistance for offshore applications, can't believe my front tray made of that looking at state of it.

Scotty, if you want a cad model for the cnc machine let me known I recently got some panels water jet cut, just sent them a cad model and they did the rest.
