I don't know if you noticed or not but in the recent "sportscar" SCCA and Toyo decided from input form the spec miata community to bring back the Toyo RA-1 as the spec tire for spec miata.
(Which in my opnion is a dumb idea, I believe that tires are to be tested and in spec sereis to introduce new tires, not a regression, the R888 is a faster tire if you know how to set it up, but ohh well.)


So for those guys that liked the RA-1 and never came to grips with the R888, it looks like you might have a chance to find new RA-1s again soon.
