The well known SX-3 is a very good example. Holger Reinert could finish third on the world championship 2001 and B.A. Arnaldi second on the European championship 2003. These successes encouraged us to continue the development of the SX-3.

Therefore the version 2004 is equipped with several new parts as for example a new rear axle, spherical drive axles, new shocks and several carbon fibre parts. Especially the new rear differential assembly makes maintenance easy.
This provides problem-free handling of the car which means a lot to competition drivers. Furthermore the higher position of the differential gives perfect alignment of the drive shafts to the axle outdrives. For smoother transmission.
