BSA Racing Wheels (CNC Machined)

   

Recommended for pinewood derby races when the local rules allow for lightened wheels but you need to maintain all of the outside and inside markings of these official BSA wheels.


Inertia Lite Racing Wheels
from Derby-Worx

$26.95

>

Wheel Mass reduced by 46 % down to a mere 1.4 grams.  They are the lightest wheels on the market with full BSA markings inside and out!!!

These are official BSA pinewood derby wheels milled on a computer controlled CNC lathe to a tolerance of an incredible 0.0005 inches outer wheel and bore diameter.  A perfectly round wheel and wheel bore make for the smoothest ride down the track possible.  The lighter wheel starts faster.  Extensive weight reduction and perfect roundness make for a light, super smooth wheel and a super fast car.  The step in the outer hub has been removed and the outer hub itself has been coned, a unique step to reduce the contact with the axle head further reducing friction at this vital contact point.  The inner wheel hub has been coned and straightened and the wheel bore has been precision reamed to size for absolutely straight tracking of the wheel.   These are the lightest wheels on the market for which the BSA exterior and interior markings remain.

 

*BSA exterior and interior markings remain.

Recommended for pinewood derby races with minimal restrictions on wheels. Rules must allow for lightened wheels and the markings removed from the interior of the wheel.


Pro Ultra Lite Racing Wheels
from Derby-Worx

$37.95

>

Wheel Mass reduced by 72 % to an amazing  1 gram !!!

These are official BSA pinewood derby wheels milled on a computer controlled CNC lathe to a tolerance of an incredible 0.0005 inches outer wheel and bore diameter.  A perfectly round wheel and wheel bore make for the smoothest ride down the track possible. Wheel hub has been coned and straightened and the wheel bore has been precision reamed to size for absolutely straight tracking of the wheel.  The huge weight reduction makes for an incredibly fast start.  The perfect wheels for a truly dominating pinewood derby car. 

*BSA exterior markings remain.

 

Recommended for pinewood derby cars where the local rules do not allow lightened wheels but you want the outer hub step already removed.

Pro Stock Wheels
from Derby-Worx

$19.95

>

Wheels are sorted by mold number and the wheel surface machined.  The step in the outer hub has also been removed and the outer hub has been coned.  The wheel bores have been machined to a consistent diameter to make sure all 4 wheels sit evenly on the track.  The perfect choice for those races where you cannot use reduced weight wheels. 

These are the new official BSA wheels for which the outer wheel surface has been milled on a computer controlled CNC lathe to a tolerance of an incredible 0.0005 inches outer wheel diameter.  A perfectly round wheel makes for the smoothest ride down the track possible.  The coning of the outer wheel hub is a new technique developed by DerbyWorx to provide an ever so slight ridge for the axle head to ride on and reduce the surface contact between the axle head and the outer wheel hub.  

(When the axles and wheels are inserted into the car body with a proper gap, there are no visible differences between these machined BSA wheels and regular non modified BSA wheels.)  

*BSA exterior and interior markings remain.

 

 Recommended for pinewood derby cars where the local rules do not allow lightened wheels and you want to race as is or to modify the outer hub yourself.
(see our pro tip)

Precision Stock Wheels
from Derby-Worx

$12.95

>

Wheels are sorted by mold number and the wheel surface machined.  These wheels can be raced as is or you can remove the step in the outer wheel hub which can be easily performed with the Pro Outer Hub Shaver.

These are the new official BSA wheels milled on a computer controlled CNC lathe to a tolerance of an incredible 0.0005 inches outer wheel diameter.  A perfectly round wheel makes for a smooth ride down the track. 

(When the axles and wheels are inserted into the car body with a proper gap, there are no visible differences between these machined BSA wheels and regular non modified BSA wheels.)  

Pinewood Derby Pro Tip: These are the exact wheels we start out with for our pure stock league cars as the step removal process is easy and we prefer the tighter gap between the wheel bore and the axles.  For the combination pack with the precision stock wheels, the Pro Hub Tool and the Pro Outer Hub Shaver, we include instructions on our own modified technique to not only remove the step in the outer wheel hub, but how you can further reduce the friction between the axle head and the outer wheel hub.
