Uneven spring rate will be the result if you run uneven holes.

Consider this photo to be the far hole in the swaybar being loaded with the longer leverage arm.



Now, consider this to be the close hole loaded and the shorter leverage arm.



Notice they are not equal? Because effective resistance is not equal across the bar. I hope this helps to convince you that handling will be different left to right.
