Here are some pictures from my rear wing and skirts. I took a mold from original rear bumper for the rear skirt. Then I made the center parts for it. The car has a removable towing hook, and I wanted to have it usable. The center part was removable, which covers the hook.
The rear wing shape was very difficult to get symmetrical, and it took hours to twist the skeleton to the shape I wanted. When that was done, I started to laminate the fiberglass. Finishing of the surface was quite demanding, because the fiberclass was very rugged.
