Modified Sedans represent one of the most technical and competitive classes within the Australian speedway landscape. Governed by Speedway Sedans Australia (SSA), the category bridges the gap between production-based racing and the purpose-built space-frame chassis of Super Sedans. The class is defined by heavily modified passenger cars that retain the original roof, A-pillars, and mid-section of the body, while featuring sophisticated suspension setups and high-performance engines. These cars are predominantly rear-wheel drive and often powered by fuel-injected V8 engines or high-capacity six-cylinder units, producing significant power for the tight confines of dirt oval tracks. The racing format focuses on technical precision and driver skill, as the rules allow for significant suspension tuning to navigate the changing track conditions of a clay or dirt surface. The National Modified Sedan Title is the pinnacle event of the season, rotating through different states and drawing the best drivers from across the country to compete for the prestigious Australia #1 plate. Because the technical regulations allow for a variety of makes and models—including popular Holden Commodores, Ford Falcons, and even older models like the Chrysler Valiant—the class maintains a strong connection to Australian automotive culture while providing intense door-to-door competition.
