Cornering stifness

What does cornering stifness mean?

Basically, if your inner wheels have sufficient (however you want to define that) contact with the road surface, your cornering stiffness is good. The better your contact, the more lateral acceleration your car can cope with, the higher your maximum cornering speed (if the surface has no bumps ).

Thank you for the giyf but I dont see that any of those links have anything to do with the iformation you have given me
Do you have a valid source?

That's not the definition I learned

For small slip angles, the tire's lateral force increases linearly with slip angle. The slope of this relationship in the linear region is the cornering stiffness; steeper slope = higher cornering stiffness.

How about the non-linear region?

[Lycoming]

Then, it's non-linear and can't be described by a single value for slope? you can still determine a cornering stiffness value by taking slope out of the data between data points, but it's not a very useful thing to do outside of the linear region, wherein it has certain performance implications.

If the non-linear region means the tire cant produce more lateral force due to too much slip angle right? And id ita really non-linear, how are people able to drift cars if its that unpredictable?

How about this then:

P.S.: Sorry, had the wrong definition in my head.

Yeah, but what does this have to do with the thing you just said?

[Lycoming]

non-linear does not necessarily mean unpredictable.

non-linear does not necessarily mean unpredictable.

How can you predict something that doesnt go up/down linearly?

[Sebp]

As I said I got confused

Shame on me

Shame on me

I am also confused
Shame on both of us

You run loads of tests and establish a working mathematical model for your parameters.

No I mean when you are driving it, like drifters
