  • Modern motor vehicles especially sports cars have a low ground clearance due to design. This is also necessary to achieve better aerodynamics and center of gravity. Due to the low ground clearance problems arise that affect the practicality of such vehicles. For example, can overcome obstacles such. Thresholds lead in traffic-calmed zones and parking garage ramps by placing the vehicle body to damage the motor vehicle.
  • Motor vehicle struts of known type consist of a combination of a shock absorber and a spring such as a coil spring or an air spring. These struts can be adjusted in height limited by a lower spring plate, which is usually attached via a thread on the shock absorber, is adjusted by a rotational movement in height. As a result, the spring - and with it a piston of the shock absorber - is moved along the axis of the shock absorber. But this attachment can also be done by a groove, the spring plate in position holds and predetermines by their location a certain vehicle height.
