My point is a question about design not fabrication: what are the planned angles for the top, bottom defuser, and how are you accounting for the stock tumblehome of the sides? Top and bottom have ideal parameters according to the "template" and other posts available here. Accounting for the tumblehome can be vexing and is one reason I postponed my trunk-lid project indefinitely.

I love the feedback you are getting re: fiberglass and steel. Good stuff, that advice.

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.
