You should learn to use the oversteer to your advantage, In a front drive car the way to keep from spinning is the opposite of what you are currently doing. Mash the go pedal and point the fronts where you want to be. The tail will follow. Not the fastest way around all corners since you are bleeding energy while sliding, but a good way to get around some of the tight stuff that would other wise be painfully slow. Turn in... make a sandwich... rotate and go. A good example of where to use a drift would be a tight Chicago box, or set of 90° turns.
Also getting some front camber on a McPherson strut will help when you autoX.
