Known within the Sports Car Club of America as the FM class, Formula Mazda is one of the more affordable open wheel racing classes available today, slotted between Formula F and Formula Continental in terms of both cost and performance. The series originally grew out of a group of chassis built by Hayashi in Japan for the Jim Russell Racing Drivers School, which made their debut at the 1984 Long Beach Grand Prix.

The car features a welded steel tube frame chassis and is powered by a sealed 1.3-liter Mazda rotary engine connected to a Hewland five speed gearbox. All Formula Mazda cars all use the same tires, springs, dampers, and anti-roll bars, though some adjustability is permitted. Much like other spec classes, the relative parity between each car means that driver skill is the key factor in a racer’s success in Formula Mazda. Let’s take a closer look at the particulars of the FM class.
