Perfect for all designers:

Many have figured out that CDs and DVDs make great wheels but the biggest challenge is attaching a CD/DVD wheel to an axle. Doc Fizzix manufactures a special insert that is designed to fit perfectly inside and CD/DVD so it can fit on a 3/16-inch axle. Spacers are made from a light weight flexible rubber that also acts as a cushion to smooth out the performance of a vehicle. Spacers can also be used to center an axle between the frame of your vehicle in order to cut down on the "side-to-side" movement of an axle. This is a hard to find item and is really a "must have" part for making a mouse trap powered racer. Complete step-by-step instruction guide.

The Essential Project Packet includes metal thrust washers designed to help decease friction and high tech Kevlar string so that your vehicle can out perform the rest of the competition giving your racer the winning edge.

As with all our top kits, The Essential Project Packet includes our "easy-to-wind" and "snag-free " string release system that will not tangle or snag for increased performance, a technique developed exclusively by Doc Fizzix.
