A-MOD Class

This weekend, the ‘other‘ member of Demaras Racing will compete in an autocross event in the Push It To The Limit series. Chris Demaras will turn laps in the 1999 Mazda Miata track-day car that he and Daniel used all year long to practice at tracks like Shannonville and Mosport. Darryl D., President of the Mazda Sportscar Owners Club which runs the series, informed Demaras Sr. that the MX-5 would run in the A-MOD class. So what exactly are the car classifications that maintain fairness and competition?
