Everyone who has gauge ring issues and hasn't contacted Jeremy directly yet please PM me so that I can give you his contact info. Below is the quoted response I received from Jeremy when inquiring about the ring fitment issue.
Two of your members have contacted me already. There may be a problem with our current stock of E36 rings. We are unsure and are looking into it at this time. Please have any members with this issue, contact me directly so I can help them out.
We will replace any rings that have fitment problems. Sorry about this... we have never had this problem before! We are going to reorder a whole new batch from our supplier.
