You might say WTF is out to in, and I'll respond with a brief silence... here let me explain out to in. Technique is widely use for grip driving and is highly effective in going fast through the corners. The idea is when your going to tackle a corner you should position your car in the outside line. Then as you enter the corner with your superb braking you steer towards the inside line of the corner.
Whether its a left or a right hander you can still apply this technique. So the basis of out to in technique is choosing the outside line before you enter a corner, then when you're about to enter the corner aim for the inside line. So how is this technique apply in your drifting. Well to put it simply you can drift much faster and you'll clearing corners much smoother when you apply this technique. When you target the inside line you should be sideways at this point; you just need to hold the steering to clear the corner because you should have entered the corner with a plenty of speed.
That technique is used all the time by the pros and you should try it when you get a chance. It's one of the ways I can drift easily when I apply this technique, its not hard at all it just takes practice. Sooner or later you will be able to do this with ease of effort.
