Back to the FD thing.....it all has to deal with friction. We all know, the more friction the tires have against the road, the more it is going to accelerate.
In drifting, it takes power to spin the wheels so you can get sideways, and the friction from the tires are what "push" the car around the turns.
The diff allows for a car to have different wheel speeds through a corner. If both wheels rotated at the same exact speeds, they would have the exact same friction levels.
When you allow one wheel to rotate at a slower speed, it is removing the forward friction, for lateral friction (grip).
Imaging coming out of a turn on a race track (grip driving) and you had a welded diff, we know that the outside of the wheel rotates faster, but on a welded diff, they rotate at the same speed. So the outside tire gets 100% of the grip it can acheive, while the inside tire is actually spinning faster than the road, which in turn, is wasting friction.
Now imagine that on a drift car that is sideways, the more friction you can get, the more grip you are going to see. That goes the same for decel. Let me know if that makes sense or need more explanation.
and again, this is my understanding for diffs, i can be wrong.
