DAMN YOU FORZATHON!!!!
Every time I think I'm done with drifting they pull one of these.
Any way, I highly recommend getting the 1974 Toyota Celica GT. Then grab Don Joewon Song's tune for it. He has 2 tunes for it, I personally used the old one but either should work.
Then go to Settings > Difficulty. Turn off both Traction and Stability control. Then change the transmission to Manual.
For which zone to use, if you have the Hot Wheels expansion I would recommend one of those as I found them to be significantly easier than the Blizzard Mountain or base game ones. Otherwise, just try some out till you find one that doesn't make you question your life decisions.
As you drift, keep it in a low gear as you want power to spin the tires, not speed to send you flying off the track.
If, like me, you hate drifting, hopefully this will help you get through it.
