Corner balancing

Corner balancing is the process of shifting the weight carried by each wheel on a car to an optimal value. A properly corner balanced car will handle evenly in left and right turns. Conversely, unbalanced handling occurs when front-to-rear weight distribution is not equal for the left and right sides.

Streetcars are rarely corner balanced and typically have no provision for adjusting spring height. On the other hand, corner balancing becomes much more critical for race cars due to their higher spring rates and the need for better handling and performance. If there is have uneven mass on your wheels, then the tyres will all have different levels of grip, which can lead to an unpredictable car. 

The goal of corner balancing is to have the same front-to-rear weight ratio for both left and right sides. Therefore, the car will handle the same through left and right turns when the corner balance is correct. That is the goal. The process measures wheel weights and plugs them into the Corner Balance Equation. If there is an imbalance, one or more spring heights are adjusted. The wheel weights are then remeasured, and the process is repeated until the imbalance is resolved.
