Your looking in the right area,Suspension is the most important thing on the car for drifting and to have a Good running car..have you done regular maintenance stuff?? like changing oil,belt's,brake pad's and bushing's ..etc.. Make sure everything is in good working order and up to par before trying to drift..Another thing you should look into is Stainless steel brake line's and some good Rotor's. After you get it in good running order,Go out and try to slide around in the rain in a nice open spot "parking lot's" or go to one of the Event's that are Held etc.. and then after you get the hang of it and you feel like you could use more power then start to upgrade motor stuff..
