1979 Joest 935J

Inspired by the Kremer brothers, Joest built their own version of the 935 for the 1979 season. Like the factory cars it featured intakes in the C-pillars and also had a slightly different front profile.

One car was campaigned by Liqui Moly Joest Racing and won the 1980 Daytona 24 Hours outright as driven by Reinhold Jöst, Rolf Stommelen and Volkert Merl.

A second car was built up for Electrodyne and raced with Momo livery in the USA. It had a fairly miserable 1980 except the season ender at the Daytona 250 were it won outright. Later in the season it was joined by another 935J.

Various other cars were outfitted with the ideas presented by Joest for Spot-Oil-Racing, Vegla Racing Team and DeNarvaez Enterprises for the 1981 season.
