My solution is for those drifting dummies like me myself, who have played the game for over 100hrs while haven't got 3 stars in even one single drifting PR stunt.
I tried HS Neofist's solution for some time and decide to give up because I cannot drive with the traction control turned off and made no progress at all...
So I move to the Hot wheels world, going to the half pipe at the north end of the Hot Wheels Island map. Here is the solution:
1. Turn the stability control and abs braking off, drive along the pipe and gain some speed. Speed is important, other wise the drifting may turns to burning tyres which is annoying.
2. When approaching a bend, drive a little left (right) to the suggested line if it's a left (right) turning, and turn left (right), no handbrake as it won't count.
3. Your car will start to drift with no obstacles to worry about, and easily get an "ULTIMATE" drift message on-screen, but hold until "Hot Wheels drift" prompt.
4. Do that at the next turning, you may get 3 or 4 Hot Wheels drift from one end to the other end of this pipe, so it's easy. I don't recommend reversing back to drift again at the same turning, because when the "Hot Wheels drift" prompt, it needs some cooling down to count.
(I got like 40 "ULTIMATE" drift as I traced it in the "record-technique" interface, but no achievements pop out. When turing to the xbox app on pc I found this achievement progress is only 60%.
The reason is in Hot Wheels world, "Ultimate" drift isn't ultimate, they added a new category called "Hot Wheels" drift, which can be obtained when holding the drift just a little longer.
I went for another 10 Hot Wheels drift and the achievement pop out. Even dummies can do huh
