This is a tough one to explain.
1st off, forget the E-Brake method.
For a tight 180°, I brake right at the threshold (ABS kicking in), and at the split second before turning in,
shift to 1st, turn the car, and gently roll back on the gas so the inside front tire doesn't spin.
I also come in wide, and go out narrow.

Scroll down to "The Line", it's explained there with Figure B being the proper line.
Haven't had any of those, unless you consider our "skid pad" at a test and tune to be one.
Hint...adjusting the steering wheel is costing you time.
Hold the wheel steady, and adjust the line of the car with the throttle.
