Add weights to your Pinewood Derby car. It's as easy as ABC!

Tip #14

When your pine car is completed, it should balance 1" to 1 1/2" in front of the rear axle. Position the weights to adjust the car's balance. To check the balance, place a pencil across the car and move it forward and back until the car balances on it.

Tip #24

Use Wood putty to seal the weights in a car. If you are in a hurry, use wax from a candle. It is just as strong and sets faster.

Tip #33

Try to place all of your weights in a single area on the car. This will lower the car's turning inertia.

Tip #47

If you mount weights on the bottom of the car, make sure that your car still has at least 3/8" clearance between the lowest part of the weight and the track. Our Bottom Weights are only 1/16" thick so they can be added to your car without interfering with the clearance.

Tip #56

If you use lead weights, always insert them in the car and seal with wood putty to avoid exposure by anyone handling the car. Use gloves when handling the lead weights and wash your hands when you are done.

Pinewood Derby Car Weights

The more your pine car weighs, the faster it will go on a downhill ramp. Most rules specify a 5 oz. maximum weight. Most Pinewood Derby cars weigh between 1.5 oz and 3.5 oz (depending on design) without weights so a car may need 3.5 oz or more of additional weight.

About Our Weights

Our weights are available in a variety of shapes and three different metals - Lead, Steel, and Tungsten. Each metal has its advantages and disadvantages. The following table will help you to decide which metal you would like to use.

One main difference between the three metals is their density. The more dense the metal, the more it will weigh. The picture to the right shows the the three metals and the amount need of each for the same weight. As you can see, it takes a lot less tungsten then steel for the same weight.

Here are the main advantages and disadvantages of each metal:

Advantages

Disadvantages

Lead

Soft - easy to bend and cut.
Low cost
Medium density

Should not be handled by children. If you use lead, insert it inside the car block and seal with wood putty.
Only available in one form - 1/4" cylinders.

Steel

Low cost
Can be cut

Low density

Tungsten

High density
Ideal for concentrating weight in a small area.

High cost.

Cylinder Weights

Cylinders are typically inserted in your car by drilling one or more holes in the back, bottom or side of the car then the holes are sealed with wood putty.

Lead Wire Weights

These 1/4" diameter lead weights can be easily cut to any length with wire cutters, diagonal pliers or other cutting tools. Drill one or more 9/32 " holes in the back, bottom or side of your pine car, insert the weights in the holes then glue them into place or cover with wood putty.

The package comes with 3 sections for a total of 3 oz.

These are lead weights and

Last week I ordered your 3.5 oz tungsten weight, 1 oz of tungsten cubes and graphite lube. My sons car took first place overall in his pack this weekend with time of 2.2960. We are off to the districts now! I Wanted to say thank you for getting the weight to me quickly and all your pro tips on the website! Thought I would send some pics of the pinewood derby car and trophy. Thank you!........ Proud Dad

Brandon won first place in his pinewood derby race with the help of his dad and our polished axles and tungsten weights.

Evan's dad Kip blew all the cars away in the unlimited division using our Tungsten Canopy and Razor RSX Wheels

Pinewood Derby car using aerodynamic weight

1st place overall in pack and first in the dad group. I've used your products for the past three years and went all out as this was our last year.... Chad P. Chad built his winning car with our pre-cut Funnycar, Tungsten Plates and Polished Axles.

I just bought the pre-cut starfighter, grooved axles and decals
off of you a couple weeks ago and I wanted you to know that my
son won a pinewood derby tournament. His car was the fastest
in the tournament (out of two counties). Thank you again... Zach S.

All our parts and weights have come from ABC, quick shipping, excellent products.
Over the years our cars have always done well - 2014 was Cole's big winner.
THANK YOU Dave and ABC Pinewood... Douglas B.

This is my Star Wars Rebel Alliance Speeder. ;) I won two of my four heats in our work-event "day at the races." Can't wait to compete again next year! All the best, Melissa

Just want you to know that we won the entire Pinewood Derby. 1st place out of 40 kids and I also won the Dad's event. Thanks for all of the help... Lance M

Our pack has two Bear dens. Each den raced themselves. Then top three from each Bear den raced each other to get down to the top two for Districts. After 12 or more races Jacob's car won every race but one. His pine car then raced the one that beat him to determine first and second place. Jacob's car went on to beat it. Jacob took first place in our den and in the combined Bear den race. Onto Districts!! Thanks for all the help and support... Craig and Jacob H

These bottom weights work great! I use a hot glue gun and they hold up great. I wish I found them years ago!!...Jerry B.

Thanks for your advice - we won 1st in his rank and 3rd overall out of 52 cars. We had a wedge design but I think we didn't win overall because we didn't use tungsten weights and ended up putting weights too far forward. We have a district race in a month....Colin H.

Whoo-hoo! We won 1st in our den, and went to districts! Did great there too! Your tungsten weights made the difference
:-)....Anne B.

Thank you for getting our Pinewood Derby weights on time. Jabez WON 1st place in his Bear Den. He was super excited. He just got his trophy awarded at the Blue and Gold this past weekend. We always use you every year. He named his car "Spider Rider.
...Jabez and Rita J"

We came in 7th out of 48 people in our pinewood derby race. The time difference between us and first place was .051 seconds! Not bad for the first time!....David D. (David used our axles, wheels and weights)

I'm happy to report to you that the races were last night and, with the assistance of the items that we purchased from your company, which included the lathed and matched wheels with graphite and polished grooved graphite axles along with some tungsten weights, my son Ross's pine car blew past the competition and we won first place in our pack. We had also purchased supplies for you last year, and had won first place in the pack last year also...Ken H.

Hello, I just wanted to thank you for the tungsten putty that I purchased from you. I won all of our pinewood races and ended up in 1st place. Thank you for your time... Jamie

Raced on Saturday. Got 4th place out of ~120, not bad. Son was a little disappointed, as 1st 2nd and 3rd get trophies. But I was happy with how we did (Kevin used our steel cylinder weights).... Kevin D

I want to give you an update on my grandson's performance using your tungsten canopy and wire weights. His derby car won first in his age group and second overall for the whole pack! Thanks for your good products..... Scott K

I recieved the tungsten canopy yesterday.Tthank you it is exactly what I needed!..... Kristine S

Sam won the pinewood derby for his pack. Car was a least a car and a half in front of his competitors every time. He wants to start on his next car..... Steven S.

My son's car won every race in a field of 32 cars. Most of the other cars came well prepared but we were just that little bit better. Our design,tungsten weights,dome, putty and wheel set up killed it. Thank you. ..... Rick D.

The dome weight worked out great as a central piece of weight. Simple Drill out and then glue to attach.... Ronald S.

Your weights are dense and compact - just what I was looking for. We ended up winning the fasted in den.... Ben F.

My son won den, pack and district. The great thing about your tungsten putty is that small adjustments in weight can be made just before the race without tools. Scales are different in each event so your car could weigh heavy or light but it doesn't matter, add or remove a little putty and you are all set.... Fred T.

The cylinders are excellent Pinewood Derby weights if you know how to bore a hole in a piece of wood. I don't but a friend helped and I'm very satisified with the results.
... A Derby Mom. :)

We used the stick on weights to fine tune our car. They worked great and the adhesive really stuck! As a side note, they can also be used for balancing ceiling fans..... Gary N.

My eldest ended up winning Pack Champion and middle son scored Open Class Champion, the latter of which was with a car equipped with the weight we ordered!..... Jayson B.

I used the 3oz tungsten disc for my son's district pinewood derby car this year and he won 1st place. I was wondering if this item will be available again next year...... Kevin A.

The disc is extremely dense and hard. It helped my son win 1st place in his pack's Pinewood Derby.
..... Johnny P.

The cars for my grandson turned out great. My first attempt at a pinewood derby car and we got second place. My goal was to just not have my grandson embarrassed. It was a good day. Thanks for the weights, which did help. Thank you...... Gerald N.

This was worth every penny, we won first place out of 67 cars!...... Anthony W.

My son had his very first pinewood derby and won second place. He usually has a hard time finishing more complicated projects, so this was a big help to him. The car weighed five ounces on the dot. The dome took to the spray paint he used nicely.
...... Ed J.

The tungsten putty worked perfectly. I could mold it to fit inside the cavity I carved. And it was easy to remove some when we found that the car was slightly over weight........ Sam K.
