The best advice I can give you is to put several hours away and find out what works best for you. I have tried some of the set ups on this webpage way back when and they didn't work for me. I started toying with my Vitz just for fun and found out what worked and what didn't.
My advice is to do the same.
Do you need to pour endless ammounts of money into your car in this game to drift? No. Just turn off the ASC/ TCS crap and understand weight transfer and all that jazz.
