Since both pictures are identical, I assume both are 15 inches. I think the old red box one is sold as a new Parts Maker product line. It'll probably look too small even on a tiny Miata model. 16" wouldn't look too bad, but it'd be better to have a 17". I'll keep on looking.

If the worst comes, you can cut the spoke part and graft it on a 17" rim.

As for the quote, could that be the Japanese phrase: Jinba Ittai? It's nothing to do with a horse dying, but that has been the Miata's concept since it's birth, so I'm almost certain I'm right. In Chinese, the characters are probably the same, but pronunciation would be different.

It's composed of four characters human-horse-one-body (make sense, right?) and if you look up those words, you should be able to find them.
