These official BSA axles have been machined to remove the burrs and crimpmarks as well as taper the head, eliminating hours of work!  As the Mark Rober Pinewood Derby YouTube video mentions, these axles are polished and can optionally be bent to 2.5 degrees!  Mark concluded that rail riding is one of the keys to derby victory.
 
On the fastest Pinewood Derby cars both rear axles are canted so the wheels will migrate away from the car body to eliminate wheel-to-body friction and increase speed.  This canting can be accomplished by either drilling the rear axle holes at an angle using a drill fixture (like the Turbo Jig) or bending the axles.  The dominant front axle (or steering axle) is also bent so that you can easily adjust the alignment of the car to either roll perfectly straight or turn into the rail, significantly improving stability and speed.  These super fast axles are already polished and with optional bending you can quickly and easily install and blow the doors off the competition!
 
Make sure to grab a set of lightened wheels (if allowed by your rules); as Mark points out, these are one of the main factors contributing to Pinewood Derby speed!
 
If you prefer to polish and bend axles yourself, a Turbo Bender and Turbo Axle Polish Kit are the best options on the market!!
