2020-07-27 - Official Miata Width

Based in the rear wing width rule I am trying to get an official answer on the width of the OEM NA Miata. Since our fenders are wider we can't use that to measure. 

Champcar measured both a spotless unmodified NA and a NB.  Both were 65.9 inches.
Wings can be no wider the stock OEM dimensional width as reported by the Manufacturer or the specification website at
