How to calculate race corner weight & weight distribution

The Race Corner Weight & Weight Distribution Calculator works directly from your race-car measurements to produce a full setup breakdown — calculate total race weight, front/rear and left/right balance, individual corner percentages, and cross weight from four wheel scales.

How the calculation works

The four scale readings are added for total vehicle weight. Front, rear, left, and right percentages divide the appropriate pair of corners by that total. Cross weight uses right-front plus left-rear, then compares that percentage with the selected target.

Example

With 780 lb LF, 720 lb RF, 820 lb LR, and 780 lb RR, total weight is 3,100 lb. The car is 48.39% front and 51.61% rear; left/right distribution is 51.61%/48.39%. RF plus LR is 1,540 lb, or 49.68% cross, which is 0.32 percentage point below a 50% target.

Frequently asked questions

Is this calculator specific to one racing series or rule set?

No — it performs the underlying physics/geometry calculation, which applies broadly. Always check your specific series' technical rules for any mandated minimums, maximums, or measurement procedures.

Pro Tips for Race Corner Weight & Weight Distribution

  1. Record the conditions (fuel load, tire pressure, ride height) each time you take these measurements, since setup values are only comparable under matching conditions.
  2. Re-run this calculator after any suspension, ballast, or fuel change to see how the setup shifted.

Common Race Corner Weight & Weight Distribution Mistakes to Avoid

  • Treating a single measurement as the full picture — cross-reference this result with how the car actually behaves on track.
  • Comparing results taken under different conditions (different fuel loads, tire temperatures, or track surfaces) as if they were directly comparable.
