2WD drifting is an excellent throttle exercise for the races. And that's my 2 cents. I watched a Swiss (or was it Swedish?) Mini-Z championship, everyone there drove with some kind of slip angle, it was quite insane. In the video closeups, these guys are going around the bends, but the steering wheels face forward, i.e. the rear is doing the turning. I want a piece of that skill, and meanwhile, have a little fun and try challenging the AWD drifters.

At the very least, your reflexes will improve very quickly.
