Ideal Rear Toe Curve?

Makes me question how ideal my curve is set. Suspension is corner balanced, but never had the toe curve precisely measured with a dial. Ive got all the spacers used/stacked and though I believe that was not recommended from Megan, the idea was to get the most compensation possible to run close to parallel with lower control arm for least toe influence, to compensate for my 2" drop and ive run that way for about 3 years now. I know I have substantially reduced the amount of toe influence by doing this along with the ride height, but i question if im actually getting some undesirable toe out under suspension compression, potentially causing my rear to still air on giving way under load prematurely, rather then being more balanced traction bias at the limit. This is with a 255/295 stagger mind you. I run 0.020"? total static toe in. .010 a side. At my ride height your talking approx 1.5" compression stroke available, so I cant imagine there being much chance from going from static toe in to toe out in that short sweep, but I honesty dont know. Your findings make me question that.
I also noticed 2 toe curve changes from factory ride height going through compression, from out to in from in to back out, so reducing the ride height to eliminate one of them was the first part of the equation. Why the suspension geometry was constructed this way makes little sense to me, seems like a bad design.

Honestly I have limited complaints with the factory toe curve. After its all said and done, it may not make a difference, what I have done. Just slapping the small bushing in and walking away would be a step in the right direction for me.
With two inches of lowering, I would definetly use the larger bushing. Both bushings might be too much, and too much correction is worse than not enough imo. As I found out too much correction reverses the factory curve. Toeing out on bump is not good.
I'd say you have two options. Get a bump steer gauge, or try removing the small bushing and drive it. You may or may not notice. If you want any factory toe data, let me know. My ride height is at 13 3/8, 1.5 extension or 2.0" of compression is the range I have data.

Something I will consider for sure. I am at 12.75" height.
