WHY IS DRIFTING IN SHIFT 2 SO DIFFICULT?😫

I Bought a shift 2 unleashed for $3. And I've been playing this game for about 2 weeks by now. And I'm already having problems and that problem being is drifting. I Already complete some drift events, but WHY is it almost impossible to drift? Like I go easy on the gas but still is like the car wants to go by its own. Is there any tips for me to know to drift in this game? I've played a lot of racing games and I know how to drift but this game takes to a new level. LOL.
