Next generation Azenis tire is coming soon!
Grassroots Motorsports has done an evaluation I believe (due out soon) , and rumor is they are fairly close to RE71R performance.
Launch Schedule (US availability; quote from TR rep on Miata.net):
We have the most recent news on the Falken Azenis RT660 launch schedule.
The normal disclaimer: this is still tentative and anything can happen between now and then. Tires are not yet on the water, and we don't even have enough information to build TR part numbers or take preorders. Plan accordingly.
That being said, here is the plan, as of 1/17/2020.
