History

The GKW Group C 2 prototype was designed and built by the Italian genius, engineer and racing driver Gabriele Gottifredi in cooperation with the Alfa Romeo Formula 1 specialist who built the Niki Lauda Alfa Formula 1. GKW Race Car is a unique car, only one specimen in the whole world. Chassis number 001/88, the race car was designed for the Swiss Driver Claude Haldi, who raced several times in Le Mans with many different racing Porsches, up to Porsche 934 and Porsche 935. Gottifredi also raced with a Porsche 934 and won at Nurburgring together with Mr. Capra. The design of GKW started in 1985 and the construction in 1985/86. The GKW Group C car was created to accept all models of Porsche 6 Cylinder Engines, turbo, twin turbo or normal like e.g. the RSR engine. The target was to build a Very Light C2 car, with C1 Engine and Advanced Technologies compared to Porsche 956 and 962 that had an older and more conservative project. The original Porsche 956 engine and gearbox were used (the current owner is a gear manufacturer, so you can imagine how much attention has been paid to just that one aspect of the car!). This Porsche 956 engine is still available as a spare engine (engine number 120), zero hours with Weissach Certificate. Many other original Porsche parts were used like suspension parts, windscreen, engine accessories and so on. The rear suspension is similar to the Porsche 956 and Porsche 962, but the front one is a push rod, more modern than Porsche 956. Also Big Brembo Brakes are more efficient than the Porsche original brakes. The total weight of the body practically corresponds to that of the front hood of a Porsche 956. Besides, a monocoque including honeycomb, magnesium castings and massive use of titanium gave the final weight result. The result was amazing: 700Kg !!!!! This was obtained by using the Kevlar Body, very expensive and advanced at that time (1985-1988). The GKW race car ran in the world championship 1988 (documents available). The car was supposed to run at Le Mans, Fuji and 1988 Monza circuits, where it performed several tests but did not participate because it was under completion at the appointed date. After this the sponsors retired (due to lack of money) and the project was stopped. The car was in GKW workshop for more than 10 years before that an Italian gentleman drive purchase with all spares package. The new owner ordered a completely dismantling and parts renew to a very specialized shop: the full GKW Porsche Race Car was completely re-worked, excluding engines. The workshop that did the job participated to Le Mans 24 hours with a Group C2 years ago and today is specialized on Ferrari Challenger racing cars, Sport prototypes, Formula 3000 and so on. This specialist workshop won quite a few Italian and European Championships during the past years. This remodeling job took nearly near 3 years and now everything is new or better than new, e.g. some suspension parts was redesigned to make them more resistant and also the feet and front pedal protection was rebuilt stronger (we have not to win the world championship!) The new owner decided do not use the air-water cooled Porsche 956 engine due to his not professional driving and ordered to Rennsport (one of the 2 main expert in Racing Porches in Italy, near Modena) a thin Turbo Based on a 3,2 IMSA configuration air cooled and electronic injected, twin plug. This engine was developed, tested and electronically mapped by Rehinold Schmirler - RS Tuning in Germany, one of the 3 best Porsche Racing motorist in Germany that worked e.g. on Uwe Alzen Porsche 997 GT3 and other Porsche winner. He was the Chief Engineer at Ruf years ago and manage now since many years his own business at south of Munich. As result this engine was excellent, over 750 HP, but the owner decided to limit it at 675 HP DIN at 7000 rpm due to same reason (not professional driver), with a wonderful torque and power distribution. Original 956 KKK Turbos are used with inconel headers, made in Maranello by specialists who work for Ferrari F1). All crash test was made and the car is now ready to race and win, with its effective weight of about 740 Kg and its 675 HP DIN engine. The Porsche 956 Engine can be bought separately as spare part. The car is eligible for Group C 2 in Europe and GTP Racing in America
