Spec Miata NA6

The Mazda Spec Miata NA6 is the race-prepared version of the early first-generation Mazda MX-5 Miata, specifically the 1990-1993 NA6 Miata models equipped with the 1.6L DOHC inline-four engine, producing around 116 hp. This car is a popular choice in the Spec Miata racing class, known for its lightweight design, reliability, and balanced handling, making it ideal for grassroots racing and competitive motorsport on a budget.

In the Spec Miata class, the NA6 Miata undergoes a set of specific modifications and regulations to ensure a level playing field. Key modifications include a full roll cage, racing seat, and safety harnesses for driver protection. The suspension, brakes, and tires are upgraded to meet racing standards, with many components regulated to maintain parity between competitors. The engine and drivetrain generally remain stock, with exhaust and intake systems restricted by class rules to focus on driver skill rather than outright power. The Spec Miata NA6 is well-loved for its nimble handling and close, competitive racing, making it one of the most accessible and popular classes in amateur motorsports.
