Since I'm rebuilding the belly pans, I figured the air dam belly pan should git upgraded as well. The new air dam belly pan is made from the former engine bay belly pan. All the metal stud reinforced 2x4 wood crossbeams have been replaced with slotted angles. I think I'm around 15lbs lighter in weight overall now.
Since I have slotted angles now, I can bolt in different configurations easily.
I'm not sure if the next version will be made from aluminum diamond plate like the rest of the belly pans but we'll see...
