22" Replica OEMs?

[GBG]

Guys,

I am think ing about replacing my 20" OEMs on my 4.8is with 22" OEM replicas. Here is the EBAY link to the whhels I'm consiering.

A few questions:

1. Are there any perfomacne disadvantages to 22s vs. 20s? I suspect the ride is a bit stiffer with 22s, but that doesn't bother me. Anything else?
2. Anyone running 22s now? What you you think?
3. Do these replicas look like good quality?
4. Finally, is this too much bling? I think they look great on an x5, but maybe I've lost it!

Thanks for any feedback.
