By Winding Road Staff
September 26, 2014
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.
- Sports Car Club of America (SCCA): Referred to as FM class. The SCCA also hosts a “Pro” FM class (Pro Formula Mazda) that utilizes a carbon fiber chassis and a 250 horsepower rotary engine hooked to a six-speed sequential gearbox.
- Ride height is unrestricted within the standard adjustment range.
- Droop limiters are not allowed.
- Anti-roll bar stiffness may be adjusted within the range allowed by sliding clamps on the anti-roll bar or front bars may be drilled for adjustment.
- Anti-roll bars may be disconnected.
- Camber, caster, toe-in/out, bump steer, are unrestricted within the adjustment range provided on the car.
- Manufacturer and construction of spherical bearings and rod ends are unrestricted, but geometry and length cannot be changed.
