Agree with what was said before. A few things that I wanted to add: While auto-x is a good place to learn the limits of your car (so you can avoid any kind of sliding in the first place), maximas behave slightly different in higher speed situations. It is more likely for the tail to come out when you start sliding going 60, than when you start sliding going 30. The tail will also come out more easily when you are going slightly over the limit, than when you are pushing it way over the limit.

Regarding what to do if the tail is already sliding, there's one very important rule: Look where you want the car to go, not at the thick trees on the side of the road or other vehicles passing by.

Off course this rule alone will not keep you out to trouble, but it really does help, and it does wonders if you combine it with other skills.

Also, when countersteering, don't just steer in the diretion where the tail is sliding, point the wheels in the direction where the car is moving. Otherwise you will overcorrect, which will result in a spin even more violent than before.

That being said, if you don't feel comfortable on the road with your current setup, I would definitely change something to make the car behave more conservatively. At least reduce your rear tire pressure by a few PSI.
