That's a fine theory, with one exception. The Spitfire spec is also something
like 3 degrees positive camber. It's nose isn't especially heavy. My car
doesn't seem to float too much with the fronts set at 1 &1/2 degrees positive
(as close to 3 degrees as the last alignment guy could get it). I too though
have been wondering what the purpose of the positive camber is. I don't really
like it all that much, and it seems a degree or two of negative (like the rears)
would be more apporpriate?
