I want a factory-quality forged wheel. For the ones that were optional for the 2014-2016 E63, go here and scroll to bottom to see what these look like and their specs:

I e-mailed an eBay seller who had ones with a different P/N (from a CLS63). What I learned is the style is slightly different (maybe doesn't matter?) but somewhat more interestingly, the CLS63 used a 19x10" rear wheel, whereas the E63 used a 19x9.5". They also claimed E63 people seek these out for appearance reasons. Sure enough, this is a thing.

And here are the CLS63 forged wheels (top of page):

14 E63S: forged wheel search
Re: 14 E63S: forged wheel search
My only "problem" is the twin 5-spoke style was put on a ton of non-AMG stuff (usually in smaller sizes) so they can look somewhat unremarkable from that perspective. But I think I can just choose to not care about that and enjoy the fact that I still like this wheel style (and always have), combined with the fact that it is actually a performance upgrade (due to being forged and lighter).
