What is this a sign of? I've been messing around with front and rear track width, camber and tweak and have not found the issue yet .. Anyone have suggestions for this behavior?
I also have a theory that i need to prove out which could cause this phenomenon.

If you run the servo flat it creates a fair amount of bump steer (front tires toeing in when the suspension is compressed). If you turn in a slight bit to hard the car will lean over more and bump steer will increase your steering angle causing the car to over-steer. If you can drive smooth this effect won't be noticed because the car is not leaning over as hard.

This is just a theory but ever since I've gone to flat servo's in both my 12th and WGT I've noticed this happening. The vertical position of the links does not seem to help the bump steer affect.

I can now see why CRC uses the angled servo mounts, it completely removes the bump steer affect. The problem with this design though is controlling ackerman.
