Outstanding weights that a true to weight

CWCMarch 22, 2026✓ Verified purchase

Terrific value for weights that you might need for pinewood derby cars. I carved out a section of the car and epoxied these weights in. It's worked perfectly! Read more

Great weights for the PWD

MicahOFebruary 20, 2026

If you are looking for budget weights and do not want to pay for tungsten, these are a great option for your kid’s pinewood derby car, especially if you have more than one car to build. For a typical wedge shaped car you usually need about 3.5 ounces of additional weight to get close to the 5 ounce limit. Since this kit comes in at over 9 ounces total, it is a solid value and gives you plenty to share between builds. All you need is a 3/8 drill bit. Drill your holes, then press the weights in. You will need to use more of these compared to tungsten because they are less dense, but they are much easier to work with. On race day, if you find yourself slightly over the official 5 ounce limit, you can simply file a little material off to dial it in. That would be nearly impossible with tungsten. For the price and flexibility, these are a smart alternative to more expensive weighting options. Read more

Nice variety of sizes, enough weights for multiple cars, 3/8 drill bit makes adding the weights easy

PaulFebruary 11, 2026

I used these weights to adjust the weight of two pinewood derby cars, and still had weights leftover. A 3/8 drill bit worked to make a hole that the weights fit snuggly in, and the variety of lengths of weight meant I could mix & match the weights until I got the total weight up to 5 oz. The case the weights came in has worked well to keep track of the weights while we worked on the cars. Read more

Case is weak!

James walshFebruary 21, 2026✓ Verified purchase

Obviously weight is weight, however the lack of packaging insulation caused the plastic weight holder to break either during packaging or delivery. If your just looking for the weights great buy, but if you are going to use the plastic case for storage better look elsewhere. Read more

Works good

Customer 34March 12, 2026

These are cheap steel weights for kids to use on their pinewood derby cars. I got these for the pinewood derby workshop for our pack for the kids who needed weights and they worked well. They are not premium weights but are cheaper than tungsten putty and a lot safer than lead. They are smooth and can be dropped in a drilled hole and covered with plastic wood or white glue. I would recommend still having some tu8ngsten putty on hand at weigh-in to micro-adjust your car's weight to exactly 5 ounces. Pros Great value for budget weights Variety of weights for customization Well-machined and safe to handle Convenient packaging for storage Cons Less dense than tungsten, requiring more weights Not pliable and moldable like tungsten paste * If you are not familiar with Amazon Vine, it is basically an Amazon review program where they send you products for free** and you give your honest review of that product. ** These items are not actually free as Vine members pay income tax (~30%) on the items they receive. I don't order anything from Vine unless I actually intend to use it. I think this is important for you to understand because it means I don't order an item just to provide a fake five-star review to a company. If I review something as excellent, it means I actually enjoyed using it or it fills its intended purpose correctly. Items that don't meet my expectations will be reviewed accordingly. Read more

Good selection and quantity

BLSLBJanuary 14, 2026

My first and only pinewood derby experience as a young scout was a complete disaster. My car barely made it to the finish line. That’s when I discovered the importance of weighting your car. Now, as a grandparent, I have a chance to redeem myself and ensure that my grandson has a more memorable experience. When I found this weight kit, I was impressed by the variety of weights it offered. Each weight was well machined and cut, resulting in clean, burr-free edges that made them safe and comfortable to handle. The 3/8” diameter weights were ideal for selecting and inserting selected combinations to tune my car. Although there are only four lengths, the quantity of each size should be sufficient for finding the perfect combination for my needs. The weight set is also conveniently packaged in a nice plastic box for storage. I believe this quality weight set provides sufficient selection and quantities to cover any scenario I might encounter. I highly recommend it. Read more

Great variety of sizes and weights

Woodland ElfJanuary 27, 2026

These are a great value and look fantastic! Not as heavy as tungsten, but for so much less money, it’s hard to see why I would want to go back! These function exactly the same: drill the correct size hole, add a dab of glue and press them in. The various sizes add a lot of adjustability and because weight needs to be in juts the right place to be competitive, it’s critical to have that kind of variety on hand! Read more
