hey that's a good idea for saving weight! I'd buy one too. I know of the CF rear diffuser, as you wrote.
How much weight would it save? 5-10 lbs?

From the pictures that I took and what I saw, it looks pretty flat except the diffuser area. Well there are some NACA scoops. There may be some small ridges that could channel air and create a better venturi effect, but they wouldn't have been big. I will look at my pictures when I get home.babak said:Is the undertray flat and flat or does it have curves and channels to stream the air properly and create downforce?
Flat. The air channels are the diffuser in the rear.babak said:Is the undertray flat and flat or does it have curves and channels to stream the air properly and create downforce?
For an undertray, you'd be better off to use a carbon-kevlar weave, or lay kevlar under the exterior carbon layer. This will increase the impact resistance.scot said:CF for an undertray might be a big no-no for street driving. The stock one can take a fair beating, where cf will probably just shatter on any impact. Potholes, speedbumps, you name it...

Actually, this part is slightly wrong. And it's hard to explain without pictures...usofrob said:So, to extend this even more, the rear top spoiler is curved up to create a pressure on the front, and less pressure on the bottom by forcing the air on the bottom to travel farther to reach the same exit point at the back of the spoiler. Faster air has lower pressure so, it gets forced down.
Definitely. Compressible fluid flow (near supersonic and supersonic) is a whole new story. The aerodynamics become very different.Gunman said:All this changes once you go super sonic though, then knife edged leading edges are more desirable.
