Grigg and Goob the idea of running the shackle to the rear isn't for bump steer it is because as the spring is compressed it grows in length pushing the axle away from the solid mounted eye and toward the shackle. So assuming that the vehicle will spend most of its time going forward if the shackles are in the rear the axle will move a little bit away from the impact that caused the spring to compress. In the off road world guys will often move forward mounted shackles to the rear. It dose make for a softer ride and tends to break fewer parts.
