Bump / Roll Camber – Suspension KPI

Bump camber (or camber gain) is a measure of suspension camber change with wheel travel and is expressed in degrees of camber change per metre of suspension travel (Deg/m).  Roll camber is calculated in the same way as bump camber except that the wheel travel is a result of body roll.

The graph below shows a bump camber curve from a double wishbone suspension developed with RACE. The on-centre bump camber is high at -30.3 Deg/m which will contribute to good wheel camber control during cornering.  The curve shows excellent linearity over the wheel travel range of interest contributing to linear vehicle behaviour with different levels of body roll.

This KPI page is only a brief overview. To learn more about this and other KPIs, including KPI values used in industry, real-world examples and best-practice guidance, please refer to our courses below.
