you be fine, just mack shore that the rings are well made and not cheap stuff.
I had hub rings before and had no issues.

Forgestar wheels do require hub rings, which are provided for you with the wheels.
Hubcentric rings are perfectly safe, as long as you get the right size.

I'll send you over a PM to discuss further.

Hub rings are forbidden on all BMW cars! You'll never get the wheels balanced.

I agree 99%.
it is very hard to make a good fit hub ring.
I was very lucky on my ACS type 4 wheels with the 4 hub rings that I had and did not get any problems.
Over the yeas I have seen many cars with hub rings that do not fit and have problems at high speed eg in the 100km to 120km
