Ever since his Championship debut in 1952, Salvadori would experience retirement after retirement. Out of the ten races contested between 1953 and 1956, he would retire early in every single one of them. But this all change in 1957, when he signed with Cooper achieving only one fifth place at RAC British Grand Prix. However, 1958 (as teammate to Jack Brabham) was his most successful season, finishing fourth in the World Drivers' Championship for Cooper, behind Mike Hawthorn, Stirling Moss and Tony Brooks. Over the course of the season, he would earn two podium finishes, including a second place in the Großer Preis von Deutschland. However he was not retained by Cooper for 1959 (when Brabham would win the first of his titles) but drove a privately entered Cooper, as well as the works Aston Martin, in which he achieved two sixth-place finishes. The Aston Martin was a traditional front engined car, which was soon outclassed by the Cooper rear engined concept. He did, however, win the London Trophy at Crystal Palace with a Formula Two Cooper. The Aston Martin team continued into 1960 but again without success and Salvadori also continued with the privately entered Cooper.
