Australia’s Premier Drag Racing Champion

Graham Withers is Australia’s Premier Drag Racing Champion from the 1960’s and 1970’s.

During his racing career Graham broke every outright speed and elapsed time record at every drag racing strip across Australia, and was Australian Champion on three Occasion in a race car that he himself built.

After retiring in the mid 70’s Graham turned his attention to business with the same passion, drive and commitments he displayed during his racing career.  Capitalizing on his racing experience and know how, he established a retailing operation for high performance automotive components.


But Graham wanted to give back something to racing, and due to his desire for continued improvement he developed and built a new all steel crankshaft Vibration Damper for high performance vehicles.  This component later become the world’s best seller.

Graham was appointed to the position of International Advisor representing the society of Automotive Engineer (USA/Australia), in which he served for over five years in addition to managing his own successful international business as Group President of the Cyco Group of Companies.

Graham’s drive for innovation and continued improvement has never diminished.  After several years of research, evolution and testing, Graham has led the development of a new light weight aluminum MMC (ULTALITE®).
