They are symmetrical, however if they left the factory not balanced properly, or if the bolts/nuts were not weight matched, you would have an out of balance situation. They're supposed to be balanced, but QC is not always perfect. I have no idea how one would check, but with the kind of quality issues that seem prevalent with aftermarket parts today, I wouldn't be surprised if these kinds of situations become typical.
