Swaters made his debut in the 24 Hours of Spa in an MG co-driven by his friend and racer-turned-journalist Paul Frère, entered under the Ecurie Francorchamps banner. In 1950 Swaters, Frère and André Pilette established Écurie Belgique, a banner in which they prepared cars for themselves and other Belgian races, both in Grand Prix and sports car racing. Swaters himself raced a yellow Talbot-Lago in several events, including two World Championship rounds, the 1951 German and Italian Grands Prix.
