BMW doesn't make wheels in Taiwan, never seen such a full info stamped on the rim,replicas I guess.Your pictures are tiny, so can't tell for sure but it looks like M logo is missing on the rims as well. Don't know if you can find the original weight of the bare rim, may be in ETK?
I think this is what you've got here
