independent rear suspension


independent rear suspension
(IRS) A suspension system where the two rear wheels are sprung independently from each other. It has the advantage over a beam axle suspension because the unsprung weight is reduced, the ride and handling over rough roads are improved, and a larger trunk with a lower floor can be placed between the wheels.
