In this book, the reader learns the essential differences to the passenger car through the analysis divided according to assemblies. This gives him the tools to apply the detailed knowledge he has acquired to the design and development of competition vehicles. The chassis determines the driving behaviour and thus the "DNA" of a racing vehicle like no other assembly. Starting with the tyre - the decisive mechanical component - all the components of the wheel suspension including steering and braking system are presented and discussed. The focus is on the double wishbone and suspension strut axles. The design of wheel suspensions starts with kinematic considerations, leads via component design to considerations of the vehicle dynamics. Ultimately, the maximum forces of the tires in the transverse and circumferential directions are to be exploited while keeping the vehicle controllable.
