Just because there is a shim somewhere doesn't mean changing a shim makes an adjustment. Go ahead and try different shims and you will see it doesn't change the handling of the car.
How would changing how far the shocks are tilted change the handling as an adjustment?
The setup sheet for a YZ2 does not have a place to list these shims as an adjustment, where are you seeing that different shims are being used?
