The Spec Miata (SM) class is intended to provide the opportunity to compete in low cost, production-based cars with limited modifications, suitable for racing competition. The rules are intentionally designed to be more open than the Showroom Stock class but more restricted than the Improved Touring class.

"Spec cars, such as SCCA Spec Miata, and now NASCAR -and increasingly Formula One- take the car out of the equation and it becomes more driver vs. driver. This is the purest form of racing, and in some cases, such as Spec Miata, it might not draw a crowd, but so what? We're talking pure sport. I predict that in the next two decades, every major type of racing will be a spec series." - H.A. Wheeler

The 1990-1993 1600cc, 1994-1997 1800cc and 1999-2005 1800cc Mazda Miata (2008 specifications) has been approved by the SCCA for Regional and National racing in all Divisions. The cars will be using a Bilstein shock with an adjustable coil-over suspension with Eibach springs and sway bars (front and rear, adjustable), steel braided brake lines. Toyo, Kumho, Hankook and Hoosier tires are in use in the various regions.
