I knew that I could avoid this thread, alas.....
The heat and bend is great 20's thinking that I used well into the 70's;
until I knew better. Turn the steering and watch the upper control
arms twist. NOT a good way to go.
I get enough neg. camber by slotting the upper fulcrum to frame holes,
using PINNED offset upper A arm bushings, and slotting the later
(yes, some TR3Bs came with them) control arms to move in the ball
joint. You will need the correct trunion for the 3 deg caster, which you
want.
I strongly advise against using the TR2/3 upper control arms on the
track for safety reasons.
BTW caster stagger may work at the 500, but can cause major problems
under braking, so I strongly recommend getting the two sides even Joe.
I also find toe out terrible on my chassis.
For those of you who still insist on bending the vertical links,
there is a Miata & driver that last helped me.
Who has measured the bump steer in a stock TR2/3? I would like to know
the figures.
Regards, HP
