A pretty easy mod that turned an OK figure into one of my favorites. I essentially just clipped the car's bumper at the joint. The two halves can fit into his torso to fill them in A LOT better, and make his legs more movie accurate with no kibble. In robot mode, I reversed his wheel position to make them more screen accurate. The back now folds very neatly and solidly into a compressed backpack making the figure kibble-free all around. Of course, the figure can still transform, but I have to attach the bumper piece last.
