I have the perfect hill. A mile and a quarter or more, no lights, no stops. Right next to campus. I'll mark a spot. Record speed at a specific second spot. A "coast-up" test. I'll do that first, being the less costly option in terms of time and gas.

I hear you, Frank. But I can deal with the slight hassle of the air pressure check, and I actually like the look a lot. As long as they are not a net loss aerodynamically, I'll keep at it until I have a good looking, well-fabricated pair of 'em.

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.
