FSR — Western Australia's "wings, slicks and aero" category: modern, open-cockpit, downforce-driven race cars that are among the fastest at Wanneroo, with lap records in the low 53s. The grid mixes purpose-built single-seaters and sports-racing prototypes across three classes — Formula 1000, the Radical SR3, and a prototype/Supersport class — and races for individual class titles plus Outright, FSR Masters and Cup honours.
