This patented new guard will keep your Pinewood Derby® car wheels aligned and secure race after race. Designed exclusively for BSA®, this under car plate has a ridge that slides right into the pre-cut axle groove to straighten and secure the axle to the car body. Its unique design allows for adequate track clearance and has no interference with the performance of your car. It is simple to understand and includes 4 screws per plate, making it easy to apply to the car. The guard can also be used to repair broken or chipped axle grooves. Each plate is made of lightweight plastic. When applied with the 8 screws provided, 2 plates will add .2 oz to the weight of your car. WARNING:
Choking hazard. Small parts. Not for children under 3 years.
