Toe in or out when raising front
I spent alot of time last year setting my ride height and alignment front and back. I maxed out the camber at neg 2deg front and neg 2.75 rear. Toe was set at 0deg front and back. The net hide height was 24.5 in. to the fender front and 24in. rear. The car handled superbly on the track. While I was installing my 3.6 this winter, I replaced my old bilsteins in the rear with new yellow sport shocks. Now the rear is sitting at 24.5 in. (same as front). Instead of lowering the rear (3.6 sits lower than the old 3.0) I decided to raise the front .5 in. I know the toe will change but can't remember if toe will go negative or positive. What are the chances someone may know how much the toe will change with a height increase of .5in. and which way (pos. or neg.)? I thought I remember reading somewhere that a slight toe out gives you quicker turn ins on the track. I'll ultimately end up measuring/adjusting the toe but thought I could experiment with the change in handling initially when I raise the front... Any thoughts?

In the rears, it will be effected, not so much in front. So raising will give a bt more positive toe, "OUT" and obviously a little loss of negative camber as well.

Just raise it and measure. You will want to know anyway. Using a tape measure from tire tread to tire tread, both front and back of the tire, will give you a pretty good idea what its doing. For exact measurements, yes, you would need to set up some strings, but with a tape measure, you can at least check before and after, and note the difference.

I ran zero toe in the rear of my car, but it's not a 3.6 and it was down right scray to drive at speeds.

Honestly, I'd expect the rear to settle back down to where it was before.
