Well, I have tein he's, open diff and i'm auto too (5-speed coming soon though) and i easily got sideways at dd10. The hardest part is maintaing the drift because of the open diff. I didnt use the e-brake once that day either...just relied on weight transfer/feint.
However, if your suspension is completely stock then yeah, you're gonna have a helluva time trying to get that thing sideways. Godd luck though!
