Official Pinewood Derby Car BSA Wheels, sorted by mold number to give you a perfectly matched set.

Why a matched set? BSA manufactures 18 different molds, numbered 1 to 18 but 6 and 7 are not used because the mold is worn. Wheels from these molds are randomly placed in the box.

The problem is, each mold is slightly different, creating wheels with differing bore sizes, hubs and tread characteristics. When every mili-second counts, you want each wheel to be exactly the same because small differences will make the car slightly off affecting speed and balance.

We have matched each set of wheels by mold number so you get the best performance, speed and balance. Another Winning Secret from the pinewood derby experts at Pinewood Pro.
