I did the alignment myself on my car.(That's an advantage of running an
alignment
shop) As I got the readings pretty close to what I wanted. I went by the tire
wear instead of the actual spec.
If you look at a older chevy with upper A-frames and see the shims.
It is no differant than a TR's but on the lower A-frame. You can change castor
or
camber by moving the shims and change the angle of the wheel.
Don't let the book tell you can't change castor.

Thats not what my manuals say. Hayes and the Bentley Guide both say
that caster isn't adjustable.
However Kevins idea does sound logicial to me.... Steve if you try this
i'd like to know the results of your next alignment.
