I'm already planning on using a core material like aluminum honeycomb, unless suggested otherwise. The main thing I want to know is what is the BEST carbon fiber types/styles to use. I know it will require just a little flex as the stock unit does, but it still needs to be incredibly stiff and strong.  I'm already prepared to fail as I know this is usually only done on very high end supercars so I imagine it will take some trial and error. I'll be using machined solid aluminum inserts to reinforce the areas where bolts go through and would normally crush it.
