1977 Kremer K2

Upon seeing the factory 935s and what was possible using the 930 platform, the Kremer bothers from Cologne built up their own version. Their first car contested the World Championship of Makes in 1976 and in the following year, an updated version known as the K2 was further modified.

Compared to the Porsche 935, the Kremer version was much more slab sided and featured fences along the top of the rear fender to direct air to the rear wing. Many of the details found on the K2 were directly ported over to the much more successful K3. These included the reshaped rear profile which used a second window and running boards which better controlled air underneath the car. Unlike Porsche’s fibreglass, Kremer opted for Carbon-Fiber/Kevlar composite. These were made by Design Plastics.1

The K2 is distinguished by its short cut-off front nose section with square headlight housings. It was first driven by Bob Wollek in Vaillant and was quite successful in the 1977 German Nation Championship. The following two years it was contested by Team Willeme and won nearly 20 races.
