A former EM participant, Greasemonkey, posted a good short thread on a kammback he built for his Civic VX hatch in 2013. He said it more than paid for itself over 80,000 miles of subsequent driving. Here is a photo of the final build. This is I think a good visual approximation of a lot of the advice you are getting.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
