Some 4.7 and I'm pretty sure most 4.9s might have issues clearing the case. There are some disparities in casings from the factory. These disparities can cause some rubbing of the case against the ring. I don't like the idea of spacers between 4+5. Basically this is what I found. A little "adjustment" was needed. I don't know how far "gone" it all is, but the proper way would have been to take all the factory parts, the factory untouched 4.9, cleared the case and been done with it.
Here is a few pictures of what I'm talking about.
