You can maintain a drift in an FF car. The overall concept of weight shift is the same. You can even selectively lock up the rears without using the hand brake by using throttle to overpower the brakes on the front but not the rear.

Source: was taught this stuff by someone that won SCCA autocross nationals, as well as a few podiums in rally. Go to any rally event and you'll see plenty of FF cars doing every drift you can imagine through corners.
