Leaf Spring info/help?

The different arch in the springs has nothing to do with the driver being in the car! It is simply because of the way the power is applied to the drivetrain, and that has everything to do with the rotation of the drivetrain and the torque it puts on the rear end, which is the last component in line! Ever wonder why the passenger tire is the only one to apply power to the ground in a single track rear end?? Because the differential is spinning in such a way that the power is directly correlated with the rotation of the drivetrain! When the car has a Suregrip rear end, the drivers side rotation must be "reversed" to make the tire spin forward instead of backwards, which would be the natural rotation to follow the driveline! Therefore, more power is applied to the passenger side, the leaf spring must be stronger on that side because it is receiving more power!! Make sense??
