I know what you mean, but in practice this system works quite complicated. The way the links are mounted on the inside has an effect on how much they push the steering outward or pull it inward.
I found on the systems I've drawn that moving the links to the back on the inside results in a bigger angular difference between the wheels at full steering angle, and moving the links forward a smaller difference.
I'm curious to see what it does on the car, are you going to do some runs with both systems to test the differences back to back?
