Thanks for this question Wyatt. There are reasons. Brucepick is considering a higher shelf, which seems better from the aero perspective. I want an aero benefit with full trunk access and absolutely minimal visibility loss. And then there is the legal requirement not to extend past the bumper. I might push that limit an inch or so, but I get police attention for my mirror delete, so I'd rather not have it on this too.

Does anyone think this use of the template reasonable? (See pic). The zero line is still positioned at maximum roof camber, but the template lines are arranged to intersect the sides of the car. The template suggests a possibly effective lid/spoiler shape. Is this a stupid use of the template? I thought I saw someone reference using it this way.

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.
