Centre of Gravity Height Calculator

When to use it

• Compare how a change in measured longitudinal load transfer affects estimated cg height before committing to parts, setup, or strategy changes.
• Check a workshop, dyno, simulator, or trackside spreadsheet result using a transparent formula: Load transfer × wheelbase ÷ mass ÷ acceleration.
• Use the result as a setup planning number, then compare it with scales, damper data, tyre temperatures, driver feedback, and lap-time evidence. Chassis numbers interact, so one change can move several handling balances at once.

How to use it

1. Enter measured longitudinal load transfer in kg; the default value shown is 260 kg.
2. Enter wheelbase in mm; the default value shown is 2,700 mm.
3. Enter vehicle mass in kg; the default value shown is 1,450 kg.
4. Enter deceleration in g; the default value shown is 1 g.

How to read the result

Estimated CG height is shown in mm. Use the number as a calculated reference point, then compare it with measured data from the car, the part supplier, or the race environment. A mathematically clean answer can still be unsuitable if the inputs are estimated, rounded, measured under different conditions, or outside the normal range for the vehicle.

Assumptions and checks

• The calculator applies the displayed formula directly and assumes the entered measured longitudinal load transfer, wheelbase, vehicle mass, and deceleration are valid for the vehicle and conditions being considered.
• Changing measured longitudinal load transfer and wheelbase together can move the answer in ways that are easy to miss, so make related setup changes deliberately.
• Use corner-specific masses and real motion ratios where possible.
• Recheck ride heights and corner weights after spring, preload, or anti-roll-bar changes.
• Treat load-transfer and frequency estimates as setup guides, not as complete vehicle models.
