What is rail riding?
When a pinewood derby car is align to run straight, but the track is not consistently level (very common), the car will contact the center guide rail both with the left wheels and the right wheels. It will wobble back and forth all the way down the track robbing you of all your speed. Using a raised wheel alone will not fix the wobble. The raised wheel will likely contact the guide rail and start spinning. This will cancel any benefit attained from the raised wheel.
Derby Worx® came up with the idea of riding the center rail. Riding the center rail keeps only one wheel touching the track. It keeps a consistent travel down the track. Utilizing pinewood derby speed axles rail rider riding bent axle kit will let you manually adjust each axle to its fastest speed. By adjusting the wheels, you will no longer be moving back and forth motion, the only direction will be moving forward! Faster!
Experts agree that controlled rail riding will produce a much faster car. If your car consistently rubs against the inside rail all the way down the track it will be faster. To compensate for the unknown condition of the track, the car can be intentionally steered such that the raised wheel does not contact the guide rail.
For this discussion, we will assume that the left-front wheel is raised (reverse if it is the right wheel) Adjust the right-front wheel so that the car drifts to the left . This keeps the left-front wheel from contacting the guide rail. With this drift, and if the rear wheels are aligned to run straight, then only the right-front wheel will contact the guide rail. To ensure that the right-rear wheel stays off the rail, the right-front of the car can be narrowed by 1/16 inch.
Tests show that when this Rail-rider technique is implemented, car performance is consistently faster than straight alignment.

There are a problem with the BSA Wheels. I have very limited amount of sets left that are machinable that do not wobble.
Matched inner bore will not be available. #15 molds are no longer premium wheels. Please watch this video: https://youtu.be/OGlZlB_h7a4
Just to be clear, I do not sell wheels that wobble. I will not sell junk wheels. I rather have no sales, than have my name associated with junk wheels.
The wheels that you see in the video are thrown away. They are not used.
BSA is aware of the problems, I am the second person to file formal complaint. Just remember I buy from same place you do.
I have been instructed by national scoutshop not to place another order for wheels. So at some point I will run out. I have no special inside line for a better product.
