The standard BSA Pinewood Derby™ Axles from the Kit have
burrs and crimp marks from manufacturing. The axle head is not a 90 degree
angle from the shaft. This slows the velocity of the car down. We
suggest Precision Axles or using the
Pro
Axle Press to fix the flaws on your wheels.
Speed
Axles With Lubricant Groove, are precision, CNC-machined. They are
High Toleranced machined straight, round and have a smooth shaft, tapered
head and cored groove to reduce friction. Burrs and Crimp marks have
been removed. There are lubrication grooves.
