LEGO derby cars

LEGO Derby is a new, cool way to race cars!

Build a car made from Official LEGO parts and race it down a pinewood derby track.

You get all the fun of pinewood derby racing without the extensive time it takes to make a car from wood.

Just snap together LEGO parts, right?

Not so fast!

There are a few problems to solve.

  1. Commercial LEGO wheels and axles do not work on a pinewood derby track.
  2. You need the perfect wheel spacing so your car fits the lanes on a pinewood derby track.
  3. You need the correct track clearance.
  4. You want your LEGO Race Car to be fast!



LEGO parts are not made for racing like pinewood derby car parts, so a car built with LEGO parts will be slow. The plastic LEGO axles are slow. The rubber LEGO wheels are slow.

Lastly, if you've raced pinewood derby cars, you know that you need to add weight to your car to reach maximum velocity.

  • So, how do you add weight to a car built with LEGO parts?
  • How do you make a LEGO car that is fast like a pinewood derby car?
  • How can you build a LEGO race car that fits on a pinewood derby track?


The secret is Pinewood Pro's new PRO Brick Wheel Assembly specially designed for racing LEGO derby cars:

  • Perfect wheel spacing - so wheels don't bind or wobble
  • Perfect track clearance - so your car doesn't bind on the center guide rail
  • Ultra-Lite Wheel/Axle assembly that is only .11oz - means your car will have a fast start and fast finish
  • Super-fast Nickel Plated Speed Axles - we appied our proven pinewood derby winning axles to LEGO Derby Car racing

...all of these feartures were designed for speed so your LEGO race car is as fast as a pinewood derby car.

To add weight, snap on a Zinc Brick. (See the silver colored Zinc Bricks on the back of the LEGO Derby cars in the image above.)

Pinewood Pro used their engineering skills and 15+ years of pinewood derby racing expertise to design the perfect parts to bring the fun of pinewood derby car racing to LEGO Derby car racing!

PRO Brick Wheel Assembly to Race LEGO Derby Cars

The PRO Brick is a custom designed part that supports a Speed Axle and custom Ultra-Lite Wheel designed for speed. The PRO Brick, Speed Axle and Ultra-Lite Wheel are pre-assembled to give the perfect pinewood derby track clearance and the Wheel is preset with the perfect gap to minimize wobble and friction.

Each PRO Wheel Assembly weighs only .11oz (3.15g) so your car starts fast, accelerates fast and allows you to place more weight on the car body giving your car more inertia through to the finish line. Individual wheel assemblies gives more flexibility to move wheels. More flexibility means more creativity.

Just snap the PRO Brick Wheel Assembly into any LEGO part and you're off to the races.

We designed these parts for speed so your your LEGO Derby Car will be fast.

A fast car needs fast wheels and fast axles . The PRO Derby Wheel is Ultra Light, yet sturdy. The axles are nickle-plated comparable to our best pinewood derby speed axle. This new Wheel-Axle combination will make your LEGO Derby Car zoom down the track comparable to the fastest pinewood derby cars.

Lastly, you need weight, since your car flys down the track from the force of gravity. Just like pinewood derby cars, you want your LEGO Derby Car to have the maxiumum weight allowed in your race rules so your car has the inertia to speed to the finish line.

The easiest way to add weight to your car is with our new Derby Zinc Brick. Just snap this zinc weight anywhere on your car just like any other LEGO part. Each brick weighs .44oz. You can easily move this weight to adjust the center of gravity for optimal performance.

How to build a LEGO Pinewood Derby Car

If you want to build a LEGO Pinewood Derby Car, you need to build your car on top of the "pine wood" derby wooden block that comes with your official pinewood derby kit. In addition, you need to use the axles and wheels that come with your official kit.

All pinewood derby races require using the parts that come with your car kit. Your kit could be the BSA kit for Cub Scouts or the Awana Grand Prix car kit or other similar pinewood derby kit.

Winning Tips and Hints

Pinewood Derby
Tips & Hints

If you are using 3/8" round weights, drill your 3/8" weight holes before cutting out the rest of the car because it is easier to hold the full block. Always use a clamp to hold your block before drilling or cutting. Safety First!

Pinewood Derby
Wheels Tip

Lighter wheels turn easier (they require less inertia). Lighten your wheels, as much as your Rules allow, which will give you a fast start out of the gate and faster speed down the track.
