There's already plenty of great advices mentioned in here, so i'm not going to repeat any of that. But what i would like to add additionally what also matters is you should have your wheel configurated and settled up properly.
You can always explore and see what suits you the most, but a good value to start with that most people use:
FFB / Spring / Damping / Centerspring / Degrees
105% / 0 / 0 / 0 / 720 (35% ingame)
This combo works on most degrees values very well, and you can add some centringspring if you feel that suits and help you out. But having too much on that, will kinda make the wheel drift for you. So i recommend not going over 45%, but it's a matter of taste.
Also i would like to add that if your interested and dedicated to drifting, you should take a visit at
www.LFSDrift.net where you can find more advices and people who share the same interest.
