The drivers ed tips are nice, but most miss the starting point. Drifting as I understood the word and driving on wet or snowy roads are two different things. Hell drifting and driving are two different words.
Fierotech nailed it but did not elaborate: Set up your car right.
Begin with a properly aligned suspension with firm healthy bushings and ball joints. If the steering (toe) angle on the rear wheels is not set properly and controlled by the suspension; without much bushing flex (none is better), then any hope of repeatable, controlled drifting is dimmed. Rear bump steer is important here.
Fieros can be drifted just like any other car. Set up the car to handle well, then learn how to use it. You can't learn to weld with a broken welder. You can't learn to drift with a broken (or improperly set up) car.
I have had a fiero slideways on dry pavement and recovered. It was cool. :wetmypants:
