Lead Ballast
Lead ballast is used to add precise weight to a race car, typically to meet a minimum weight rule or to adjust weight distribution across the chassis. It's sold as solid lead bars that bolt or mount into the car's structure.
This 25 lb bar from Allstar is a straightforward way to add a known, fixed amount of weight. Using multiple bars in different locations lets you fine-tune corner weights and overall balance rather than just adding bulk in one spot.
Frequently asked questions
Why do race cars use lead ballast instead of other materials?
Lead is dense, so a relatively small, compact bar adds significant weight without taking up much space in the car.
How do I use ballast to adjust corner weights?
By mounting bars at different points around the chassis, you can shift weight toward or away from specific corners to fine-tune the car's balance rather than only adding total weight.
