After hardpoint tuning, less amount of camber gain observed, and less amount of toe-change reduced.   We can\'t control all parameters independently.. caster, caster arm length and steer axis offset(longitudinal) are dependend on each-other. and King pin inclin Read more

1) I) Rear sprung mass frequency based on wheel base and speed will be 1.358 Hz, time lag because of wheel base and speed is 0.10 sec. II) Front sprung mass frequency at design condition 1.131 Hz III) Front Spring rate 23.853 N/mm IV) Rear Spring rate 27.711 N/mm V) Read more

1. Wheel rate differs from spring rate because of motion ratio. motion ration generates because of suspension geometry like arm length and suspension attachment point etc. And Wheel rate = Spring rate * (MR)`square`. 2. Wheel rate measures by wheel center line consider Read more
