So I take it that a roof spoiler with side spoilers that is overall about 3+ inches long and without an upward lip might reduce drag roughly 0.008 if I do it well and get lucky. And that lowering the ride height about 1.5 inches might reduce drag 0.010 if done right and interaction between various mods is accounted for.

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.
