I'm a little surprised on a car as modern as the ND that those canards reduce drag, but I guess they work sort of like the ubiquitous "air curtains" with upward vanes that all German cars now have.
How did you decide on those numbers for toe?
Also sounds like a 10Ah battery, that sounds pretty ambitious with modern car standby power but if you drive it everyday there's obviously nothing to worry about. Have you thought about adding a solar panel to keep the battery topped up?
