Spec Miata

The Spec Miata (SM) class is intended to provide the opportunity to compete in low-cost cars with limited modifications, suitable for racing competition.

It is intended to encourage low cost, entry level, production car based competition.

Spec Miata was first approved as a regional class in the Southwest Division of SCCA in 1999 and the first race as an official class was at the Fiesta Carrera Regional, Texas World Speedway 2.90 road course on July 24, 1999, at 1:05 pm and included a starting field of four drivers: Tim Evans, Shannon McMasters, Bob Reinhardt and David Obeney finishing in that order.

The first Spec Miata race for the National Auto Sport Association[1] was held in February 2000 by the NorCal Region.

Also adding to the appeal is the fact that a Spec Miata can be raced in both SM and ITA/ITS in SCCA regional competition.

A typical race-ready Spec Miata can be purchased on the market for anywhere between $6000 and $65,000 [2] depending on race win history and specific modifications.

Race cars in the division will feature Roush Performance cylinder heads, Penske Racing shocks, Eibach springs and sway bars, Pagid brake pads, Toyo tires, and more, and will have a curb weight of 2,500 lb (1,100 kg).
