At the end of 1976, Wolf decided that the team needed restructuring. He removed Frank Williams from the manager's job and replaced him with Peter Warr from Team Lotus. Disillusioned, Williams soon left the team, taking Patrick Head and several others to set up Williams Grand Prix Engineering. Postlethwaite's WR1 was a conventional Cosworth package but with Jody Scheckter hired from Tyrrell, the team won its first race in Argentina. Scheckter started tenth, and took advantage of six of the cars ahead of him retiring. During the 1977 season, Scheckter went on to win the Monaco Grand Prix and the Canadian Grand Prix and also six other podium finishes, which enabled him to finish second to Niki Lauda in the World Championship and gave Wolf fourth place in the Constructors' Championship.
