Understeer, Oversteer, Wombling free...

Oh wait, wrong under and overs. :hehe:

You would probably get better speed out with oversteer depending on traction.

yeah, i figured we were saying the same thing, just joe 90 told me it didn't work like that, so was trying to clarify!

i'm just trying to establish if its something the driver can control? when they complain about over steer i just wonder if its because they committed too much to a corner or if its purely an effect of the car.

yeah it can be controlled, like i said sometimes you want it to oversteer to get better exit speed. It can be from the setup then or from the characteristics of the car itself or even like you said a driver goes in too hot and loses the rear end.


interesting. why would i get a better exit speed from an over steer?

In oversteer condition the rear wheels are already aligned better to accelerate out of the corner.

I remember reading an article ages ago about Patrick Head saying that if a young driver likes under steer he is not a real racer.



Yes a driver will change his steering angle to catch the oversteer. If you watch someone like Hamilton driving he makes sure the front wheel are on the racing line heading in the direction he wants to be going in. He lets the rear wheels do what they like within reason.
