The bushings will not adjust themselves without the special lubricant (or soapy water). They won't budge without it. Thus, you have to seat the car down before it dries off, or the rubber will twist and distort. BMW's lubricant takes 30min to dry, after that, no adjustment is possible. The 30min is also the accepted amount of drying time for soapy water in everyone's experience who's done this.
