I just put a set of Ichiba A-arms on my Z last week and dialed in all the negative camber the arms could give me. I have been killing the outside edges of my tires when autocrossing. (Adding air pressure was wearing the center of the tires.)

I am going to use a pyrometer to set my air pressure and camber, but I was wondering how much the a-arm adjustments are going to change my toe.

*Update*

I just went out to my "testing area" and checked the tire temps. I only got the fronts up to 130 degrees, but every part of the tire was the same temp +/-1 degree. And that was at 38 psi.

Still wondering about toe though.

 

any change in camber changes toe - how much depends on too many variables. You would need to put the car on a rack to measure the before and after

 

I thought moving the top connection point could alter toe, but I was wondering how. (the relationship between camber and toe when using the top connection point for movement)

Looking at the geometry, it seems that moving the top in, (neg camber) would cause some toe in while moving the top out, (pos camber) would cause toe out.
