Also, what is your time frame? I'm wondering if I'll have time to finish the auto CDA computing on the guino first. No biggie, but that is exactly the intended usage for it.
Oh, that sounds cool. Time frame: finish & tuft test the current profile this weekend. Then decide if it the angle needs to be eased back. Then start fabricating.

Cd - I also prefer the look of the car with the kammback extension. As for the neighbours, they're not really the mocking types. Not because of gas prices, but they're used to me doing strange things to cars by now.
