This is a Solid Axle...










This is an Independent Rear Suspension...





The animation represents a solid axle and an Independent Rear Suspension as each side rises and falls due to road conditions. In addition to the stability of an IRS on  uneven roads, there is a performance aspect of an IRS that may be missed.

The major advantage of an IRS over a solid axle has to do with the overall stability of the vehicle in different road conditions. These conditions may be uneven pavement, high speed cornering, etc. Since the IRS allows either side to rise or fall "independently" of the other side, the frame ( and therefore the body, occupants and center of mass ) remain in a relatively constant location. This leads to the vehicle being more stable.
