Leaving the system on and you can get very little wheelspin, and virtually no side slippage (yaw).

Using the button on the dash supposedly disarms the system, but in reality it only sets the parameters back a little. You still cannot get too carried away with wheelspin or doing donuts.

Removing the fuses will throw a light or 2 on the dashboard, but now you can do big ol' long smoky burnouts, and donuts galore.

I have a couple of videos up on youtube demonstrating this.
