Kingpin Inclination (KPI)
Kingpin inclination (D) was originally defined as the inclination of the kingpin. In this case, however, since the model is not equipped with a kingpin, KPI is defined as the angle between the vertical axis (A) and a line through the suspension strut. Correct KPI enables the wheels to be turned more easily and also assists them to return more easily to the straight-ahead position. Kingpin inclination cannot be adjusted
