Chassis & setupSpring & suspension

Spring & suspension

Spring rate, rate at the wheel, and the corner frequency that follows.

Spring & corner

Known spring rateEstimate from geometry

Spring rate

N/mm

Motion ratio

spring/wheel

Spring travel divided by wheel travel.

Sprung mass per corner

Exclude the unsprung wheel and suspension mass.

Motion ratio applies as its square, so a small geometry change moves wheel rate more than it looks.

Calculated corner

Enter positive spring rate, motion ratio, and sprung mass at one corner.

Linear, undamped, single corner. Geometry mode assumes a close-coiled cylindrical spring. No damping, no handling prediction.
