How recently did you order these? I ordered fronts and rears back in November and what I received didn't have the hub centric ring and I was assured that what I received was correct and hubcentric (see pictures above). I'm very confused why I would have received something different.
Might be too late to return them, but def don't test fit since they'll be deemed "used"
I'm sure if you both reach out to Bora and discuss the issue they'll work something out. Especially since they
get a lot of recommendation and feedback from mud.
