Roll centre height is measured in RACE software using a force based test.  The basis for this test is shown in the diagram below.  A lateral cornering force is applied at the tyre contact patch and ...

This key performance indicator is a simple metric to help the suspension designer to understand the steering performance of a suspension system from a vehicle manoeuvrability point of view.  The metric reports the wheel ...

Static toe link load is a measure of the load passing through the toe link into the steering system when the suspension is at rest.  The load is generated by the weight of the ...

Wheel centre longitudinal offset is a measure of the longitudinal distance between the steer axis and the wheel centre in side view, as shown below.  For steered and driven axles, wheel centre longitudinal offset ...

Bump castor is a measure of castor angle change with wheel travel.  It is expressed in degrees of castor change per metre of wheel travel.  Bump castor occurs due to the fact that the wheel ...

Kingpin angle is a measure of the angle of the suspension steer axis relative to vertical in front view. The steer axis (or kingpin axis) on a conventional double wishbone suspension passes through the ...

Static toe is a measure of the static steer angle on a tyre in plan view. A tyre is said to have positive toe when the front of the tyre points towards the centre ...

Castor angle is the inclination of the suspension steer axis when measured in side-view. It is measured in Degrees and is positive when the top of the steering axis leans towards the rear of ...

Static camber is a measure of the inclination of a tyre to the vertical in front view. When the top of the tyre leans towards the centre of the vehicle a tyre is said ...
