In the 1960s, Porsche grew into a major competitor in sports car racing, sometimes entering half a dozen cars which were soon sold to customers. Apart from the factory team, calling itself Porsche AG or Porsche System Engineering since 1961, Austrian-based Porsche Salzburg was set up in 1969 as a second works team to share the work load, providing the much sought first overall win at Le Mans, in 1970. Martini Racing and John Wyer's Gulf Racing were other teams receiving factory support, allowing Zuffenhausen to focus on development, while the teams provided the sponsorship funds and manpower to be present and successful at many international races. In CanAm, Porsche cooperated with Penske, while in Deutsche Rennsportmeisterschaft, customers like Kremer Racing, Georg Loos and Joest Racing enjoyed various degrees of factory support. After appearing as Martini Porsche in the mid-1970s, the factory entered as Rothmans Porsche in the mid-1980s.
