Preparing a stock Miata for racing includes removing amenities and upgrading suspension and safety packages. The cars used are typically the 1990-1993 Miatas with the 1600cc engines and 1994-1997 Miatas with the 1800cc engines.  Engine modifications are not permitted and the 1800cc engines must run a restrictor plate.  Common and allowed upgrades include a hard top, race suspension, cold air intake, racing tires, racing brake pads, a modified exhaust and a limited slip differential.  The specifications are strict and are enforced to level the playing field and help control costs.  The Miata is an extremely balanced car and being competitive comes down to driver skill. 

Mazda supports Spec Miata racing by sponsoring races and providing drivers with a competition parts program for stock and racing components at racer discounted prices.  Professional and amateur drivers agree that the Spec Miata is a great racecar to zoomƒzoomƒzoom around the competition.
