A method allows the rapid evaluation of physical properties of chassis elastomeric devices in a motor vehicle. A parametric controller (26) provides a parametric state signal to a elastomer control module (24), which in turn generates an appropriate electrical current signal which is communicated to a variable elastomeric device (22) which includes a magnetorheological elastomer having iron particles embedded therein and a coil operatively associated therewith. When the coil is energized by electrical current signal provided from the elastomer control module (24), a magnetic field is generated which provides predetermined variability in the physical properties of the elastomeric device (22), allowing the rapid evaluation of vehicle performance for given physical properties of the elastomeric device (22).
