Having made many carbon fiber parts, any that supply any kind of support will have only the top layer done in carbon fiber with anywhere from 2 to 4 back up layers of fiberglass. Otherwise the amount of epoxy that would have to be used would have to be very thick to give it any strength to stop flexing and cracking.
So yes Mark, you are correct.
But even still it would be much lighter than the current metal lids. I have a fiberglass front hood and it's at least 40+ pounds lighter that the metal one was. I can imagine having the rear one replaced with fiberglass would be at least 60+ pounds lighter than the current metal one....Which I intend to do sooner or later as well.
One thing I've learned from changing the front hood to fiberglass is make sure you try it on for fit before you buy it if at all possible. Which is also something I will do with the rear hood when I make the change over.
Also, when doing the front hood, you may need to add a couple of zous fastners on each side in the middle area of the front hood to stop it from bowing up at speed from air flow through the radiator.

I might be wrong but are carbon fiber hood and deck lid just carbon fiber over a fiberglass shell and not all carbon fiber?
