I was probably the first to turn the upper "A" arm fulcrum around back
in 1958 trying to get some negative camber. This move does not give
enough change in the camber. You just about have the wheel straight up
only, eleminating the factory setting of positive camber.
In the end I had to bend the verticle link to get the desired two
degrees negative. I describe several other methods of achieving a
negative camber in my first book, the Triumph Preparation Handbook,
try pages 202-205 for some more information..

It seems like it would be difficult to get enough change in camber
for a TR3/4 by reversing the fulcrum. The factory spec is +2
degrees, so it takes quite a lot to get to -2. Lowering helps a
little, less than 1/2 degree. If you shorten the upper A arms as
many of us have done, you have to remove at least 1/2 inch. I wrote
a short report when I studied the suspension on my TR3 (see
http://tildentechnologies.com/downloads/TRsuspension.PDF). There is
a neat way to shorten the upper A arms that I discovered from Bob
Kramer that does not involve cutting them in two. I can put up a
photo if anyone is interested in it. The modification is not
obvious for organizations that do not permit Heim joints, etc.

Richard's message if you missed it:
"Reversing the upper fulcrum from factory orientation pulls the
control arms in 1/4" and adds about 1.3 degrees negative camber
if I remember my calculations correctly. You can do it without
removing the control arms from the fulcrum. Just remove the four
bolts holding the fulcrum to the tower and the two bolts through
the ball joint and remove the whole assembly. Then hold the
fulcrum and spin the control arms 180 degrees then bolt the
whole assembly on the other side of the car. This keeps the
front control arm in the front but reverses the fulcrum.
Preferred camber will depend on the tires. The Hoosier A6's
that I run for autocross and hillclimb want 3 degrees. They are
225/45-15 on 7" rims. To get that much camber and to keep the
tires clear of my unmodified fenders I reversed the fulcrums and
then slotted the bolt holes to slide them in even further. I
just took the worn out tires off and the fronts wore fairly
even. The rears were also set at 3 degrees but wore more on the
inside from squatting under power. I backed it off to 2 degrees
to see how that works out. Also changed to a slightly stiffer
spring."

am looking for
simple and easy ways to get negative camber in the car.
Any suggestions
would be helpful.
