Default camber vs camber gain

just wondering ....
why not use zero camber & have increased camber gain to give the camber only when its needed ??
so there will be no camber unless the car is cornering

in general, does the camber need to be different for rubber vs foam ??
what happens when the foam wears to match the camber??? effectively nullifying it ???

You throw the tires on a lathe and cut them to make them even again. And then you have to reset the ride height as the cut tires will be shorter and check camber all over again.

Camber isn't just there to keep the wheel upright as the car rolls. Even with no body roll, more camber gives more cornering grip due to camber thrust (up to a point - every tyre will have a peak camber at which it gives maximum grip). Look at the front wheels of an F1 car; they have loads of camber even though there is almost no body roll.

So the ideal setup for maximum cornering force is one with the static camber at the peak for the tyre, and the camber gain set to keep this amount of camber throughout the cornering process. In practice this is never possible as it will be affected by tyre wear, desired roll centres, and keeping the wheel upright for maximum traction under acceleration and braking.

So like all setup parameters, it's a comprimise.

Good question. And with caster, more camber is induced when the wheel turns. Maybe something to test at the track.
