Vin,

Now can I convince you to take a car control course.. (I recommend this for everyone.)

So, here's what probably happened.

a little basic car control lesson: A car only does 3 things, it brakes, it accelerates and it turns.
Having said that, basic physics demands that at any given point, your vehicle has 100% of it's ability (TRACTION) to do any one of those three things.
- Meaning, you can accelerate with 100% traction, Turn with 100% traction or brake with 100% traction.
- you can also divide the traction - 90% acceleration/10%turning. 85% braking, 15% turning, etc. etc.

What you can not do is defy physics. You can not get 110% traction or ability out of your car. Once you have met the threshold of 100% anything that happens after that either decreases your performance (like locking the brakes,) or will throw you into a spin or understeer/oversteer.

- so now lets look at what happened to you. You slammed your brakes as hard as you could.. (using 100% of your traction to stop the vehicle) And then cut the wheel to change lanes (exceeding that 100% traction)

At this point, your braking and turning was toooo much input for the car and it BROKE FREE of stability.
Had you lifted off the brake a little, you could have gotten some steering input in because the car would not be using ALL it's ability to stop the car.

Now when your car was trying to stop full force, all the weight of the vehicle was forced onto the front tires, that's like 3000 lbs. Which was fine, until you cut the wheel. By cutting the wheel, the back end of the car which was relatively weight free broke traction and started to come around on you. By the time you knew what was going on, you were probably facing ass backwards.


- The point of all this info is not neccessarily for you to understand it all, rather, it is to illustrate that there is a clear, concise reason your car did that. Understanding why it did that is the key to helping you next time your in this situation. You can learn everything I just talked about in one day of driving school.
