MazdaSpeed Miata Part Numbers

Spec Miata is a type of racing car used in SCCA, NASA, and MCSCC racing events. The class provides people with the chance to race in (relatively) low-cost cars, as modifications are limited by rule (hence the name "spec"). While there are still some substantial costs involved in racing, Spec Miata racing is about as affordable as it gets.

Part of the reason Spec Miata racing is so accessible is that Mazda goes to great lengths to provide affordable go-fast parts for all generations of the Miata. This is a huge benefit to racers, as it's difficult for after-market manufacturers to offer affordable pricing on limited part production runs.
