The Mazda Spec Miata NA8 is a race-prepared version of the second half of the first-generation Mazda MX-5 Miata, specifically the 1994-1997 NA8 Miata models. These cars are powered by a 1.8L DOHC inline-four engine, producing around 128 hp in stock form, paired with a 5-speed manual transmission. The NA8 Spec Miata was chosen for its lightweight design, superb handling, and affordability, making it a popular choice for grassroots racing and amateur motorsports.
In the Spec Miata class, the NA8 Miata undergoes specific modifications and regulations to ensure close competition. Key modifications include safety upgrades, such as a full roll cage, racing seat, and harnesses, as well as suspension and brake upgrades for improved handling and consistency on the track. The engine remains mostly stock, but exhaust, suspension components, and tires are standardized across the class to level the playing field. This results in a highly competitive racing environment that emphasizes driver skill, making the Spec Miata class one of the most accessible and popular forms of racing in the United States.
