This was the way I learned about this years ago. High school physics as I recall.

When you spin your tires, torque is applied 90 degrees to the plane of rotation. Assuming a flat surface (no crown), the torque applied to the axle(s) is to the driver's left as shown in the diagram. The equal and opposite reaction to this torque is your rear end stepping out to the right. Happens to me all of the time.

I have a fairly extreme case of yaw on acceleration. I have a 07 Z06 with 560 crank horsepower that only weighs 2851 pounds. In second gear with a 345 tire I can slowly open the throttle near idle and at WOT and 3200 RPM my tires will spin violently. I don’t want to jump into the theory battle, I only want to add my experience. With me in the car it showed 210 pounds more weight on the left side of the car. I assumed that I was getting more left side bite causing my car to yaw right under wheel spin conditions. I added a little wedge to the chassis. Left front up half a turn and right front down half a turn. In the rear, half a turn down on the left and half a turn up on the right. Now, instead of a hard yaw to the right I get a tiny wiggle left then it goes dead strait. I did this strictly for the street and I do not track the car. I have never dragged the car but it might help there.
