the thing is, drifting is mainly about reaction and instinct. you can teach techinique, how to slide a car, how to control it, but when you're asking how to take a corner, everyone takes it differently. many people like to take the inside, feint to out then intiate a drift. many others choku-dori (basically a feint, except drifting). I kansei (basically lift off throttle while turning in at high speed, then jumping back on throttle). it's all up to your personal tastes.
