How to Calculate Corner Weight

CW% = (LF + RR) ÷ TW × 100

Corner weight distribution determines how the vehicle's weight is balanced across all four corners. Proper distribution is crucial for optimal handling, tire wear, and suspension performance.

About this tool

The BuildLockr corner weight calculator helps racers perfect their suspension setup. Use this tool to instantly calculate cross weight, front-to-rear distribution, and side-to-side balance. Whether you are prepping a track car for road racing or dialing in wedge for an oval, this suspension tuning calculator ensures accuracy. This helps drivers achieve symmetrical handling and predictable grip through corners by perfectly balancing their coilover ride heights.

Weight Distribution Reference

Cross Weight Target: 50.0% is ideal for perfectly symmetric road course turn-in left and right.
Asymmetric (Oval) Racing: Setups often target higher cross weight to optimize turning direction.
Left/Front Bias: Front-heavy cars will suffer more understeer but provide better stability.

Common Corner Weight Questions

What is cross weight?

Cross weight (also known as wedge) is the combined weight of the right-front and left-rear tires, expressed as a percentage of the total vehicle weight. It heavily influences how a car handles through corners.

What is a good corner weight distribution?

For road course racing, an ideal cross weight is exactly 50%. This ensures the car handles identically when turning left or right. Oval track cars often run asymmetric cross weights (wedge) to optimize turning in one direction.

Why is corner balancing important?

Corner balancing ensures that weight is evenly distributed across the tires diagonally. Uneven cross weight can cause a car to oversteer in one direction and understeer in the other, making it unpredictable at the limit.
