Camber
This is the wheel’s camber with respect to a plane perpendicular to the ground (Fig.2). The camber can be positive
(the front view of the vehicle shows the wheels opened upwards) or negative (the wheels are opened downwards).
The camber affects roadholding and driving comfort. The adjustment values were designed to obtain the best
compromise between roadholding and comfort.
Caster
This is the angle that forms the steering axis of the wheel projected on the longitudinal vertical plane with respect to the transversal vertical plane passing through the wheel axle ( Fig.3). When this angle is positive, the steering axis
meets the ground in front of the vertical axis, thus creating momentum that tends to realign the wheels.

The pressure inside the system reaches 20 bars and the minimum pressure switch ( ) L J ) opens.
Following occasional pressure increases (e.g. rough road surface), the minimum pressure valve ( ) L J ) opens.
The excess pressure is relieved by means of the solenoid valve ( ) L J ).
Furthermore, the ECU cyclically closes the solenoid valves for short times during vehicle operation (raising condition, see next paragraph) to keep the hydraulic circuit pressure in the range of 20 bars.
