Crossweight measures the distribution of weight between the four tires of a car. Mechanics calculate this by adding the right front and left rear weights. This percentage determines how the vehicle handles while turning through a sharp corner. Increasing this value typically makes a car tighter or harder to turn. A team adjusted the crossweight to stop the rear from sliding out. This setting remains one of the most important tools for a chassis. Professionals use specialized floor scales to get a perfectly accurate weight reading. The balance must change based on the specific shape of the track. Drivers provide feedback so the crew can find the best weight balance.
