Can anyone advise ? Do I turn the nut clockwise or counter clockwise to raise the rear of the car. I see there is a threaded stud in the center of the spring that the nut turns on. Some of the stud is inside the spring and some above it. The more of the threaded stud inside the spring vs above it would mean a higher rear once the rear is set on the tires... Correct?

Thanks for any guidance
