The first issue to solve, especially crucial for the 917, is the stability. The short tail K version (Kurz Heck) is steady but too heavy while the LH (Lang Heck) has a better top speed.
The 908.02 version, released as prototypes in 1969, is a spyder, lighter than the previous 908 coupe. Its aerodynamics is also improved by a much flattened body that provides it the nickname Flunder (flat fish).
The pilots went to prefer the LH. In 1970, the chassis 5 of the Porsche 908.02 Flunder is modified into a Lang Heck. In this configuration, it gets a nice history in endurance racing and participates in some running sequences in the film Le Mans.
This 908.02 Flunder LH prototype is for sale by Bonhams in London on November 30, lot 23.
