Its not that FF cars are not allowed in D1, they would not be able to drift well enough to qualify for D1.1.6pete said:sure! they can enter into any amateur drifting comp it wants! but when they get into the real deal (i.e. D1) they are not allowed only the rwd (pure breads if you will) enter. or if fwd can enter they don't because they know they don't stand a chance. the laws of physics wont allow a fwd car to carry a power slide down a long strait, simple as that.
Sliding a FF car sideways is not competitive drifting, especialy now at the level that the sport has progressed to.
