[Fot] Amount of front and rear negative camber?

[jim hearn]

Hi Bill,
 
Thanks for a great response.  I have used the shoe polish on the
sidewall to check for tire turnover and will put a temp gauge in my
routine.  I have a laser no contact type and I assume these will work as
well as the probe type.  What I was looking for on the alignment
settings was a starting point.  I have only had this TR6 about a month
and a half.
 
Referring to another post you sent me, I think I am far from a show up
and drive person.  I have been working on this car since the day I got
it.  I do do autox/race on a budget and try to do the most myself and
get the most bang for the buck.
 
Thanks again for your responses, Jim

Depends on your tires and the amount of camber gain you have. If you
want to do it via measurement, you need to determine the camber gain and
the typical deflection of the suspension. Not easy to do. Otherwise, get
a tire temperature pyrometer and a skid pad (A big parking lot with no
neighbors) and go round in circles until the tires heat up to more than
110. Measure the temperature at outside, middle and inside of each tire.
Make sure you do circles in both directions. If the middle is hotter
than the inside and outside, your tire pressure is too high. Decrease
tire pressure until the middle is the same as one side. then read
everything again. If the inside is more than a few degrees hotter than
the outside then you are too negative. Or vice versa. Lather rinse
repeat. Then use a camber guage to measure what you have, and there's
the right answer.

Here's the wrong one, but it's easier: Radials: 3 degrees negative, Bias
Ply 0 degrees.

On a '74 TR6 being used for autocross (no street use at all), what is a
suggested initial set up for the amount of negative camber front and
rear.
Thanks, Jim
