Pro's - You can do skidz au, and come on, who doesnt want to light a big dirty patch of rubber down.
Con's - Besides the mechanical issues that have been mentioned. Anyone who owns a skyline, supra, or a RX7 can do better skids and think your a twat for not doing it properly, 90% of people in subis will look at you like your a twat for ruining a perfectly good awd car.
