RE: de-driftify? possible?
It's bound to be a nitro RS4 of some kind, and yes, it's perfectly possible to de-driftify. You'll find that the diffs are probably locked, so that's a good place to start (apart from the obvious grip tires which can just be bolted on). Also, if it was setup properly, the suspension will be too stiff for grip driving. You will probably need to change out springs and oil to get any kind of handling out of it.
I probably made it sound more involved than it is. Try to free up the differentials, put a set of grip tires on and take it from there.
