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 aftermarket manufacturers to offer affordable pricing on limited part production runs.
Whether you're a Spec Miata racer, looking to give your personal driver a little more "oomph," or just curious about pricing out your own Miata racer, here's a list of the MazdaSpeed parts available that are compatible with Spec Miata racing.
NOTE: Racing rules can change. Please double-check compatibility with the official rules.
