Pinewood Derby Speed Wheels - precision lathed

Why would you want lathed wheels?

BSA Lathed Speed Wheels

BSA ultra lite wheels

When a race can be won by a fraction of a second, it is important that your car has every advantage.

  • Outer tread is precision lathed to perfectly tune and true this wheel, removing all imperfections while being careful to keep the beads along the wheel rim.
  • Inner tread is precision lathed, once again removing all imperfections.
  • Hub is precision lathed to perfectly tune and true the hub to the center bore.
  • The hub is squared so there is a perfectly flat surface meeting the car body, eliminating wobble when the wheel hub touches the car body
  • The wheel rim is squared so there is a perfectly flat surface when the wheel rubs the track center guide. This reduces friction and reduces the chance of wobble.
  • Wheel is lighter, giving you a fast start out of the gate because a lighter wheel requires less energy to get started than a heavier wheel.
  • All four wheels come from the same mold so they are perfectly matched.
  • We make all these improvements and carefully leave all BSA lettering, tread beads and markings intact.

outside and inside treads are lathed

Why lathe the treads?
Because it is like a car with unbalanced wheels!
Wheel imperfections will cause uneven rotations, however small, with each revolution, reducing speed.
With precision tread lathing, your wheel is perfectly round and trued to the center bore giving you maximum speed.

Wheel Tread is "Trued"

What is a "trued" wheel?

Precision lathing "trues" the wheel tread to the axle center line,
meaning the tread is now perfectly concentric with the axle,
giving you perfect precision rotation.

hubs are squared

Why square the hubs?
Once again, imperfections in the plastic cause friction where the wheel rubs against
the pinewood derby car body, slowing your car down.
The hub is squared because friction is reduced and wobble is reduced if two perfect 90 degree surfaces meet each other. The BSA wheel hub is rounded (coned) too much! We flatten this surface to reduce friction and wobble, therebyincreasing your derby car speed.

Wheels are Lighter

Why do you want lighter wheels?
Lighter wheels are easier to turn, giving you a
faster start and increased speed
as your derby car races down the track.

Wheel bore is reamed

Why ream the wheel bore?
Like the other areas of the wheel, the bore has imperfections and
may not be trued to the rest of the wheel. When the bore is reamed,
your pinewood derby car wheel rotates perfectly about the axle.

Outside wheel rim is trimmed

Why trim the rim?
The rim has imperfections that slow your pinewood derby car whenever the wheel rubs
against the center rail.
Trim the rim, reduce friction and increase your speed!

Wheels are a Matched Set

All wheels are not created equal. There are many slight differences between each mold when they are made. To achieve optimal performance, your wheels are matched as a set, giving you perfect balance.

Wheel Tread is "Trued"
to Gain Speed

Just like the wheels on your family car,
your pinewood derby car wheels need to be
balanced and tuned for optimal performance.

Imperfections in your wheels cause your car to bounce, vibrate and turn to one side or the other,
resulting in lost speed.

To increase your car speed,
we have precision lathed, tuned and mold matched your wheels,
resulting in increased speed.

      Tips & Hints

      Spin each wheel on a polished axle with graphite and count the number of revolutions. If a wheel wobbles, try spinning it again. If it still wobbles, get another wheel that does not wobble.

    • 1st Place!! Thanks for the everlasting memories you have made possible!
      - Williiam from IN

    • We got a "Most Realistic" for the Humvee and an 4th place with the "wedge." You would have thought my seven-year-old twin grandsons had won college scholarships! I was a hero. Thanks, again. I'll probably be back next year, Lord willing.

      Hey Joe- Just wanted to pass on the good news- and a few nice pix. We ended up in 2nd place out of 63 cars racing. Not too bad, and we'll be at district in a few weeks.
      - David from IL

    • This is my son's first Derby car as a Tiger Cub Scout. We had a lot of fun working on this together. Even though he didn't place it was a rewarding experience. Next year we plan to build something even more unique and perhaps a little more challenging. Thanks for a great web site!
      - Shawn from CA

    • Last year we took 1st place in our pack I am sold on your speed axles and speed wheels. We raced the car in his elementary school, and he won 1st place in the whole school. Thanks so much!
