Pinewood Car Derby Weights Kit






Will these weights fit standard pinewood car builds?
Yes. The weights use a 3/8″ diameter, which matches a common drill size and can be easily installed in most pinewood car designs.
How do I avoid going over the weight limit?
The mixed set includes 1/2oz, 1/4oz, 1/8oz, and 1/16oz pieces, making it easy to add weight gradually and stop exactly where you need.
Are these weights easy to use for beginners?
Absolutely. Start with larger pieces, then fine-tune with smaller increments. This step-by-step approach helps reduce mistakes and makes tuning more beginner-friendly.
PRECISION TUNGSTEN CAR WEIGHTS ā 3.25 oz incremental tungsten cylinders help you dial in the exact weight of your pinewood car or other wood race car. Perfect as derby car weights for scout racing, pack events and open-class track competitions
HIGH-DENSITY ā Our derby car weights are made of high-density tungsten, which is 1.7 times denser than lead alloys and 2.4 times denser than iron. So these compact 3/8 inch derby car weights let you pack more mass in the rear of your race car, move the center of gravity back, store more potential energy on the ramp and improve finish-line speed
FOUR INCREMENTAL SIZES ā This tungsten derby car weights kit includes 4 Ć 1/2 oz, 3 Ć 1/4 oz, 3 Ć 1/8 oz and 2 Ć 1/16 oz cylinders (12 pieces total). Multiple sizes make it easy to fine tune balance, add or remove weight on race day and place tungsten exactly where your wood car needs it
BUILT WITH FAMILIES ā Each tungsten derby weight is machined with rounded ends without sharp edges, comfortable to handle while sanding and installing. Ideal for scout workshops and family build nights where kids and parents shape and tune their wood race car together
EASY INSTALLATION ā tungsten weights cylinders are 3/8 inch diameter, which is the standard bit size; you can just drill a hole in the desired area of your wooden car, then insert the weight and paste it in place to use
