here's my guide to drifting:
find a big space and practice initiating drift, try 2 things, overtorquing the rear wheels and unsettling the balance of the car. all those techniques above stem off these 2 concepts, they are just different ways of doing it. u can use the clutch, drivetrain friction, braking, steering etc. no point going through them all step by step and trying to do exactly what they say. just get a feel for how to lose the rear end, the characteristics of each technique. then put it into practice on the track, from there u have to experiment with controls and how they affect the car and how u can use them, once again, not much point trying to explain this to someone who is still trying to get down the basics of drifting.
the main thing you remember is that if you are interested in replicating what you see on vids such as D1GP and what ud consider main stream competition drifting, you need to know the criterias for judging. Line, angle and speed, and in chasing battles: duplication and proximity. its hard to gauge how your doing with all this, and its not always a good idea to base urself of what u see in drift servers.
