Need some guidance. I want to lower the suspension on the front of my 355. I've searched and read the different threads regarding lowering, it's just that none of them give the details regarding my issue. I have the wrenches required for the lock collars on the struts, although after loosening the lower collar I can’t get the bigger collar to turn as there is pressure on it from the spring. I am trying to do this with the struts still on the car. Is this wrong, do I need to remove the assembly and compress the spring in order to adjust the collars? I borrowed a spring compression tool from AutoZone however it will not fit on the springs with the struts on the car.
