Love your Prop Racer System but need more cars without another track? These sets fit the bill by including all the parts, hardware, and rubber motors needed for extra racers. Choose between a set of four (one each of the four Prop Racer designs) or a set of 28 (seven each of the four designs) – enough Prop Racers to wind up your entire class!
