[yellowpanel]

I am the owner of the yellow panel. I can tell you that my car is lighter then stock and I didn't take any steps to make it light. Remember there is no back seat, no door framing, no glass and no rear bumper beam. There is a heavy plywood deck under the carpet and plywood side trim panels. Also heavy sound deadening and a heavy steel beam in each side. I could have easily used Aluminum, light weight composites and high tech stuff, my thought was the weight would help the ride. It does and gives the car a very solid feel. I would gladly post some photos If I could figure out how.
