assuming that you are driving a rear wheel drive car.
part 1-you are into a right turn, well, smash in the throttle,
power overcoming the reARS, car stars to slide left, apply oppo
lock( to the left), balancing the gas pedal, so the slide
holds.
part 2 - transferring to the right - clutch in to abruptly cut the
power to the rear wheels. keep the oppo lock on. this causes the
rear wheels to suddenly regain grip,this throws the car sliding in
the other direction (top the right) as the suspension rebounds. at
this point,smash the gas again and let out the clutch. this causes
the rear to lose grip again. you continue sliding right,remember to
apply oppo steering lock to hold the slide, in combo with gas pedal
moderation.
