No clue.. not sure if anyone else does. Interesting part of the article says Miata will keep the RR (at least for now). No mention of CMC.

Looking at the Maxis online it is $300 a set cheaper so that's certainly nice. Googled some compares to the RR and hard to say if it's a "better" tire or not... guess we need some feedback from the giant group of E30 guys in Texas
