front > natural frequency than rear - can do rear x 1.15 = front
effective spring rate at the wheel finding
> frequency = > stiffness = < grip - soft suspension / soft and high temp tires > grip
→ front understeer bc of the grip - obviously more grip means more potential to oversteer
passenger cats 1.0 - 1.3, sports sedans 1.2 - 1.5, sport cars 1.5 - 1.8
more damper dependent ^ when softer
race cars w aero > 1.8 frequency - > stiffness so vehicle handling < performance
Caster - increases steering effort and feedback (good) - increases negative camber gain with steering angle (x,z plane outboard) - having wheels lean into turns and induce camber
pos - lean back - DB, preferred
neg - forward
built-in -
more caster = more steering torque
helps self center steering
Kingpin inclination - caster but front of the car - angle of steering axis from vertical
camber gain while steering
> KPI = positive camber gain - not good - we want negative camber gain on the outside wheel
