Spec Miata/Racing

SPEC MIATA RACING 

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 currently races both sprint and enduro eaces where available.Mazda Miatas in model years 1990 through 1993 with 1600 cc engines, model years 1994 through 1997 with 1800 cc engines, and model years 1999 through 2005 with 1800 cc engines have been approved by the SCCA for Regional racing in all divisions of the SCCA. The class was approved for National SCCA racing beginning in the 2006 racing season.As its name shows, Spec Miata is a 'specified' class. This means that the rules for allowable modifications to the car are very strict. The class intends to put drivers on a very even footing by making their cars as identical as possible. Because of the support of Mazda through Mazdaspeed Motorsports Development, the wide availability of the car on the used market, plentiful and inexpensive parts, and the simplicity of maintenance on the cars, Spec Miata has become a very popular class.By using a specified rule set, Spec Miata has taken the guesswork out of deciding which parts are best to use while deterring competitors from 'outspending' each other. For example, competitors have no choice of what types of tires, springs, shocks, sway bars are allowed. Modifications are extremely limited to the drive train and the different model years are equalized through weight limits and throttle restrictor plates.
