#1 - Come into corner, start turn
#2 - clutch in
e-brake until you feel the back end break
#3 - clutch-out HARD on gas (keep the wheels straight... AWD drifts do not take place with opposite-lock)
#4 - (here is where you guys will hate me) If the car starts to hook up during the drift, pop the e-break quickly while still on the gas. YES, this warms up the center diff a bit, but keeps ya pointed in the right direction!
E-brake will only "hurt" the center diff when the power is down, if you clutch it when you handbrake you take the stress off of the center...
