Trying to add real weight without chewing up a ton of space under your Pinewood Derby car? 
 
Pinewood Derby tungsten packs a lot of weight into a small area, so you can tune your build without the underside looking like a messy stack of chunks. This 2.56oz (72.7g) bar is a solid option for Cub Scout families building their first fast car and for experienced racers who want more control over placement.
 
Bars for Smart Weight Placement
 
One of the biggest benefits of tungsten is flexibility: because it’s so dense, these tungsten bars let you place weight where it fits best for your design. Start by checking your rules and target weight, then weigh often as you go. A lot of builders push weight rearward for potential speed gains, but you still want the car to track steady – especially on rough tracks. 
 
Keep things even side-to-side, and lock the bar down – so it can't creep or rattle loose on race day. And if you're chasing that last little bit of weight, mixing a bar with smaller pieces can help you land on the number without going over.
