Fig. 4.5. Points of measurement of height of a road gleam

Measurement of road gleams of the car is necessary for observance of accuracy of angles of installation of wheels as these corners slightly change depending on car height. Points for measurements of a road gleam are shown in the figure 4.5.

The R1 size is measured between a floor and an axis of rotation of a forward wheel.

The R2 size is measured between a floor and an axis of rotation of a back wheel.
