As I said a few posts above, and has been said many times on this forum before: to kill all traction aids, unplug the Bosch yaw sensor. It's underneath the center console plastics, not far from the cup holder. If you had small hands and already knew exactly what it looked like and where it was, you could probably just pull out the cup holder and reach in and unplug it, but worst case just remove the center console first. It's only a handful of screws and plastic clippy things.
Without the yaw sensor VDC, TCS, and ABLS are all completely disabled, but you still have ABS brakes. Mine's been that way for a while now. If you're slipping the wheels on purpose on a regular basis, especially cornering for a road course and/or auto-x, the ABLS will really screw with you randomly when cornering near the limit.
With all that stuff out of the way, you can abuse your tires all you want and control it manually. I can just floor the car from a roll in, say, 2nd gear, and burn through a gear or two ("cleaning off the tires"
) and keep it straight with the driver inputs, and the car doesn't balk or try to do anything funny at all. It also won't save you when you're too hot in a corner, but that's a good thing - gotta learn to save yourself. VDC has horrible ideas about the right way to save it anyways :P
