Yes, didn't write about it because that is the same MX5 "Super 20" SEMA show car they had on display last year....just repainted in brighter color this year. There are threads here and many places that covered that for many pages of discussion last year, just Google "Super 20 MX5" for lots more on that car. See the Sema Flares thread (CLICK HERE)
for pics of same NC last year, and in new color this year toward the bottom of the thread.
That wheel was custom cut and welded for the show car, not a production item (Enkei not planning to make any).
