alignment experts - quick question about front toe & ride height
 

What are the effects upon front toe settings and ride height? Does TOE go more negitive as the front goes higher ? and should the fuel tank be 1/2 full or full when measuring toe ant the front? 81'SC

The answer is that "it depends".
Assuming stock ride height and no bump steer kit, lowering the car would decrease toe in on a stock SC.
The steering rack is slightly lower than the point on the spindle where the ball joint attaches. Raising the spindle will pull the rear of the wheel inward.
At least that is how it works on my SC :-)

As far as the fuel level, ideally you would want to set it up to mimick driving conditions as closely as possible, so a half full tank would split the difference I guess.
I would think that having the drivers' weight in the seat would make more difference. If you are trying to get it that close, a corner balance would be necessary also.
