Rolf Stommelen
Despite never winning as a driver at Le Mans, Joest ended his driving career in style. After winning the 24 Hours of Daytona in a Porsche 935 and on the Nürburgring with his Porsche 908/3 Turbo in 1980 (both with Rolf Stommelen), he went on to win several German DRM races in 1981 with a mighty Porsche 935 "Moby Dick". He retired after winning the Kyalami 9 Hours with Jochen Mass at the end of the year.
