C3 of Year Finalist (track prepared) 2019
If anyone hasn't reviewed BeeJay's solution to the front air splitter/ extended spoiler, you're really missing out.
IMHO, THIS in plastic is exactly what the world of C3s needs. Start with the Pace Car front spoiler and then a plastic splitter based upon BeeJay's design, 2 bolts, and a piece of aluminum angle iron and some rubber for a spoiler that gets nice and low to the ground.

Then a rear diffuser that starts just behind the diff / spring...

Adam, it may interest you that I have done quite a bit of reading on splitter materials in planning for this, and plastic is not regarded as a good choice - too heavy and not stiff enough. Plywood or various composite materials are the most common/popular choices for stiffness against weight, with plywood winning for most due to its wear properties (won't splinter into a million pieces on bumping a curb etc.) and cost. I was surprised too, but plywood seems to be a good choice. Some people are using plastic as a thin layer underneath as a wear surface.

For any underbody/belly trays, plastic aluminum is still preferred as the rigidity isn't as important there, though; right?

Birch plywood is often made from thinner laminates and is both light and strong. They use it quite a bit to make lightweight guitar and bass amplifier and speaker enclosures. You may have to find it at a real lumber supply rather than the big box stores like HD or Lowes.

Guys, I certainly think a splitter or a spoiler is a good idea, but ya can't combine them ***** nilly. In a previous post there's a picture of a splitter (which works by allowing fast moving air to create a low pressure zone) with a spoiler (which works by slowing/stopping air to create a high pressure zone ahead of it) mounted down downstream. There seems to be some serious negation/inefficiency with this combination.
It seems the choice should be made whether to keep air out, via a low spoiler, or allowing any air going under the car to remain in a high velocity state. Letting it under the car, and purposely slowing it down seems counter productive, both from an aero perspective and from a componentweight perspective.

Looks nice, but I'd be surprised if it does much - air would be too turbulent. I don't think it extends far enough forward and/or not enough has been done to smooth the airflow underneath for me to think that it would do much to improve the aerodynamics. It may reduce a little drag at the rear, but I'm doubtful that it creates any downforce.

Two Thoughts?
I have read it here that removing the rear window makes it much more quiet.
That being said, would that act as a diffuser?
Second: I just saw the beautiful Green Mamba Pro Tourer.
Very nice splitter in front.
In most shots the rear has a full wing.
I did see a video where a flat plate acts as a bolt on spoiler.
There seems to be a gap at the bottom.
That could also act as a diffuser of sorts?
I do like the idea of bolting on as much spoiler as needed!

Check out Dynamic Corvettes. com. I saw their display at Carlisle and they had some cool stuff for our cars. They had f-glass bumpers and splitters and such.
