40 Years of Business

In 1977 Bärbel and Friedhelm Großewächter made their passion to their profession.
The company Mechanical Garage was founded in Spenge , Im Soar 25. Friedhelm Großewächter simultaneously went to training school for master craftsmen.
In 1979 a retail shop with an attached workshop was opened in the heart of Spenge and a Suzuki representation was founded. Friedhelm Großewächter still took actively part at motocross races. First employees were hired and two training vacancies were created.
1983 was a meeting of the most successful Suzuki dealers in Japan and Bärbel and Friedhelm were invited .
A view years later they specialized of the sale of engine substitutes and tuning parts. The development and manufacturing of camshafts required an expansion of the Business premises Im Soar 25. To ensure a fluently operation flow we decided to abandon the Suzuki representation and the retail shop in the heart of Spenge.

In 1997 The camshaft logo TORNADO RACING CAMS gets the symbol for a registered trade mark. The camshaft machining and the development of tuning concepts in racing for several motorcycle models has been the main business .
