Notes on Height Changes/Wheel-Load Changes

Notes on height changes/wheel-load changes
When changing the height/wheel load, the following must be noted:
^ A one-sided height change causes a wheel-load change at the same time. A wheel-load change on one wheel also alters the wheel loads of the other wheels.
^ A one-sided increase in the installed spring preload (raising vehicle) increases the wheel load.
^ A one-sided decrease in the installed spring preload (lowering vehicle) decreases the wheel load.
^ A change in the wheel-load is always transferred diagonally onto the other axle side. This means that if the wheel load on one wheel is decreased or increased, the same occurs on the diagonally opposite wheel.
^ Maximum wheel-load difference from left to right on front and rear axle 15 kg.





^ Example: Rear left spring preload C is increased. In this way the wheel load: rear left C and front right B greater [solid line] rear right D and front left A less. [dotted line]
