Had a similar issue with my BMW Z3 after I loaned it to a friend
Turns out that the "ultimate driving machine" is not meant to be drifted by a newb trying to impress a girl. It is especially not made to take curb impact at speed.
My wheel would jerk to the right, the steering was wobbly, and the whole thing pulled to the right. Keeping a constant left was the only way to get it somewhat straight.
It was the tie rods, completely demolished and looking somewhat like melty pretzels.
For you, the smart money is on the tie rods. If those are bent or broken, then your entire steering geometry will be thrown off. If you have any sort of camber or toe, this issue is multiplied my a magnitude of however many degrees you have of camber and/or toe.
Fortunately, this is a somewhat easy fix with plenty of documented "how to" knowledge, especially here. Unfortunately, the sport of drifting seems to produce three common casualties:
Tires, tie rods, and body work.
The other good thing is tie rods are relatively inexpensive. Then again, "relatively" is a relative term.
Good luck, keep us posted!
