If you are going to present technical details about the new A1GP cars, then I think you should get it right mr.Watson.Just a little homework please. These cars do not have 3 dampers at the rear. There is what is commomly refered to as a third element, which links the left and right suspension and rear anti roll bar. There is also a third element on the front doing the same job. There are no ally packer shims, or any other packers as the third element has eliminated the need, as the gap is set by the third element. Support is provided by "BUMP RUBBERS" enclosed in the third element
