I don't think he is loking for tunes, just tips on how to drift.
Jayson. Easiest thing to do to start, go slow! I've watched in GT5, and have no doubt the same will continue into gt6. Just slow it down. Instead of trying to go for the full corner, all out, neverlift smoke fest, take your time and get the feel of just small slides at first. Not sure if you are a competent racer, but the same basics kinda apply. You need the right line, the right braking points, turn in, all of that still matters in drifting too. If you are going in so fast and hot that in a race you would over shoot adn run off the track, the same will happen when trying to drift. In gt5, I have a couple of cars I could suggest to start with, that drift great out of the box. Can't give the same advice yet in GT6 though, since the physics are now different, and cars don't quite behave the same now.
So, jsut start off slow, on something like autumn ring mini. Get maybe an rx7 or silvia, put on CH, and go out there and first learn how to contol the car stock, then slowly upgrade as you find yourself improving. And slow down, this is drift, not a race. A lot of people forget that I think.
