Example: What Happens When You Move Weight

Moving a 40 lb battery from ahead of the front axle (140") to behind the rear (-25") can shift weight distribution by roughly 1–2%. That may sound small, but it can noticeably improve balance and reduce understeer.

Try it yourself with the default values above, then compare it to moving the engine back or reducing front weight.

Weight Distribution Explained

Weight distribution affects how a car accelerates, brakes, and turns. Front-heavy cars tend to understeer, while more balanced setups improve handling and responsiveness.

This calculator helps estimate how modifications like battery relocation, lightweight panels, or engine swaps affect front-to-rear balance.

Even small changes (1–3%) can make a noticeable difference in how a car feels on the road or track.
