Spacers can also be used to center an axle between the frame of a vehicle in order to cut down on the "side-to-side" movement of the axle. This is a hard to find item and is a "must have" part for making a mousetrap powered racer. CD/DVD spacers comes in a pack of 20 CD/DVD spacers with a complete step-by-step instruction guide.INCLUDES THE FOLLOWING: 20x CD/DVD spacers Not just for mousetrap vehicle projects, CD/DVD spacers wheels can be use for just about every possible project you can dream up including rubber band racers, balloon powered vehicles, and so much more.
