ya, about the long turn on Trial Mtn.
Dont brake too much for it. The biggest probs i have with that corner when im trying a new car is that im a little bit tentative at first about carrying speed through the turn, and then the drift sorta falls in on itself, as you described.
Dont be afraid to try entering the turn with the gas pinned and with a huge drift angle, my 400R gets almost straight sideways at the center of the turn, and my S13 isnt far off. A little feint action and the proper entry speed and turn-in point is all you need. The worst that can happen is you spin or put a dent in the guardrail, and have to turn around and try it again.
If i remember properly, I usually start shifting the cars weight around with feint motion just after the hill-crest in the straight-away, then turn-in at the leading edge of the yellow V's on the outside of the turn such that the car starts drifting with the nose just above that yellow area on the inside of the corner at around 70 or 80mph. If you're not comfortable with feint weight transfer, just give the brakes a quick tap when u turn in to move the weight onto the front tires.
As the drift sheds some speed you'll gradually work your way to the inside edge of the corner if you've got the gas down. Dont stray too far up the track, the end of that turn has a way off pulling you into the barrier. My exit speed is typically 60-70 mph, depending how much ive had to get out of the gas during the drift to keep from swapping ends or making contact at the exit.
I dont know if i can put it any better than that.

Maybe try it, and adjust it to suit your own driving style.
Practice, that's all it comes down too. If one thing isnt working, learn from it and try something new.
