here is what i would do,
Stay on the throttle till the car transitions into drift the other way,
and use the steering wheel to give it a slight flick to get it moving in that direction.
(which means steering away from the turn, like you want to straighten, this gets the cars momentum going for the transfer, then steer back into the drift to swing the car harder at the transition.)
This little steering thing is a quick quarter turn and turn back. I have been using it for years to help extend drifts or transition.
Higher HP cars dont do this which is good, because its frowned upon by the FD judges
what engine and rim size?
