Don, definitely start by reversing the fulcrum if you can. Pretty easy to
do compared with some of the alternatives. Uncle jack's car is pretty
seriously lowered and doesn't have that kind of negative camber, so I would
guess that either the fulcrum's been switched or the upper arms have been
shortened. You shouldn't have to raise the car to achieve what you
want. I took some negative camber out of my TR-4 for exactly the same
reason and didn't seem to negatively affect the handling at Road America.
Henry, I agree. (I've not driven the track, and it's on my "at least once
in my lifetime" list)
