One of his best years was the 1957 Formula 1 season when, after some frustrating race results, often caused by technical defects, he finished fifth at his home grand prix in Monza . It was precisely this success that made up for the fact that shortly before Stuart Lewis-Evans had “robbed” him of fifth place in the closing stages of the Pescara Grand Prix .
At the 1958 Targa Florio , Jean Behra shared a Porsche RSK with him . Disappointed with the result, Behra later expressed his opinion that they could have won. But Scarlatti would not have been able to drive faster. This assignment of blame, which is unusual for sports car drivers, also spoke of the frustration of their own racing bad luck, which the French had so often before a tangible victory.
