The NB8C has a weakness in its front biased weight load. This means it is prone to oversteer while braking and makes it relatively unstable when slowing down. Satoshi Omiya has countered this problem by fitting a rear spoiler (i.e. a GT wing).


  • Some early examples of the first-gen MX-5 have a detuned B6-ZE engine that only produces 90 hp instead of the original 118 hp output.
  • By far, this is the world's best selling sports car and world's best selling two-seat car, beating the Ford Model T. As of this year, the numbers are getting close to one million units.
