imo, specially with the S with no traction control, etc., most scary moments happen when applying torque (throttle on) in the middle of a curve or bend.
When getting too fast into a curve the S still will understeer unless you were crazily fast and some lift-off oversteer happens.

I'm not sure what point you are making there with regard to the thread.
However, power oversteer, as you describe there, is much easier to recover than over steer induced under braking, which is much more sudden and violent.
Having spent half a day on a dry airfield learning how to recover the car, I discovered the best way to to make over steer happen, and what I describe above is most definitely the best way. Approach a corner at speed, brake hard, and add more steering angle quickly and see what happens. Be prepared to add and remove a lot of opposite lock very quickly indeed. Do NOT try this on a public road.
Alternatively, be cornering hard and stamp on the throttle, if a slide occurs, a quick straightening of the wheel will usually sort it out. Opposite lock is probably too much.
HTH.

my point with regard to the thread is what I´ve stated in my 2nd post. Despite the well balanced car that the S is, and despite its tendency to oversteer, I like to have more front end grip and can be sorted by using wider front tyres and playing with the pressure when you are on track.
I´d go for wider front tyres and consequently wider rear tyres (even in 16") wheels. You can get less understeer by using 225 on the front i.e. 225/40 R18, 225/45 R17 or 225/50 R16.
I´m running squared 225 in the winter with rear winter (M+S) tyres. And I run 225 fronts and 235 or 245 rears after winter.

That's a lot of effort when much the same effect can be achieved by a change in driving style and/or geometry.
More especially the case when driving what is predominantly an every day road car.

tire wall stiffness helps alot. Mushroom topping the tyres wouldn't be good imo.
18" wheels that are wider than oe with slightly stretched tyre to keep the contact patch consistent would help improve grip.
