What upgrades are necessary to make a car safe or street drifting?

Lower Control arms? Tie Rods? Struts? Lowering Springs? Anti-Roll Bars? What all is necessary to make it safe to fly around turns without snapping any parts off?|||Have a read and think about it. Different cars will have differing priorities to make them work the way you want. http://en.wikipedia.org/wiki/Drifting_%2鈥?/a>
