You change Instant center with an adjustment to either the upper control arm mounting point, either at the body or at the rear differential, or by changing the rear lower control arm mounting point at the differential. Changing the angles of the control arm mounting point changes the instant center. Also changing the front and rear ride heights can also change instant center as it changes the angles of the control arms in the rear of the car. If you drew an imaginary line through the control arms, the point that that line from the upper control arm intercepts the lower control arm would be your instant center point. Here is an instant center calculator courtesy of Baseline Suspensions.
