Although Porsche had officially ceased building new 935s at the end of the 1979 season, customers continued to race and even build newer cars with great success for several more seasons. Perhaps the very best and most successful of these private 935s is the 935 JLP-3 built for John Paul Racing by GAACO. Powered by the latest evolution of the twin-turbo, flat-six engine, it was built around a lightweight spaceframe. This was both lighter and stronger than the standard 911 chassis used for the regular 935s. To meet the homologation requirements, the roof and windshield for an early 1970s 911 were included in the design. Raced by John Paul and his son John Jr., it became, in 1982, the first car to win both the Daytona 24 Hours and Sebring 12 Hours in one year. John Paul Jr. was also crowned IMSA GT Champion that year. The unique JLP-3 was replaced by the even more sophisticated, aluminium monocoque 935 JLP-4 but this was not quite as successful.
Not quite as well known but just as special was the 935 L1 'Baby' built for and by Jan Lundgardh with the help from Porsche. As the name suggests, this spaceframe car was powered by the same 1.4 litre engine used in the works 'Baby' from 1977, which allowed the car to compete in the 2-litre class. In fact the engine used by Lundgardh was the spare for the works campaign and provided to him by Porsche. The Swedish driver campaigned the car in several World Championship rounds during the early 1980s and also at Le Mans but was not particularly successful. Eventually, he replaced the rare and fragile 1.4-litre with a more conventional 3-litre engine, which is still in the car today. Beautifully restored the one-off 935 L1 'Baby' is regularly raced in historic events all over Europe.
