If your going to learn on the internet, might as well learn from the BEST.
I present the original Drift King: Keiichi Tsuchiya
Each part of this 6 part series discusses the different types of drift technique. I believe they also range from simplest to hardest to perform. But its been a while since I watched them so don't quote me on that.
1. Side (E-brake)
2. Shift Lock
3. Power Over
6. Lift Off
Enjoy and be safe. I'd go out to a wide open parking lot before you actually try this on the track.
