I prefer to use a tier 1 car on drifting, not too fast and not too slow, good handling and great traction.
Inorder for you to get the hang if drifting, balance your speed and try to drift in the middle, don't try to drift in near the wall where the lines are, though it will have a great points in there, if you can't control your car will crash. Practise in the quick race first to see your skills, keep practising till you get the hang of it.
Hope that helps and good luck.
