Did you use longer chassis screws to off-set the thickness of the metal or is that your actual chassis and not a underneath bolt on?
I was thinking of doing something like that, but using it like a skirt, that goes around the stock chassis.
Instamorph if you don't know is a low temp thermoplastic that you put in very hot water, and then work by hand before it sets up. I liken it to a stiffer and more plastic like hot glue.
I was thinking I would roll it out like dough to get a flat uniform sheet, and then work it with a heat gun and modelling tools to get it into shape.
The car is designed to go pretty fast, so I don't think you can over engineer it. It's made out of aluminum, and it screws to the bottom of the stock chassis. It's an 1/8 scale car, so any plastic or carbon fiber wouldn't be stiff enough. It also has flexable skirt/seals to channel the air to the rear diffuser.
If I were you I would make a mold of the shape you want and vacu-form it out of .090 lexan. It's light, super strong, and you can easily duplicate it if you crash.
