on the 03 GT 1 year ago I installed a set of Sportline lowering springs and replaced the Struts in all 4 corners with monroe. After a week or so of driving the car was aligned. No problems at all for 1 year. April of this year I added a Hotckiss RSB, 17" wheels and new tires then had it aligned again, no problem. This past June been hearing the springs shift on the rear when taking corners or hitting a bump. I tore them down and inspected and found no issues an reinstalled. Again the noise continued and then recently installed new mounts on the rears, again the noise continues.
What am I missing? Next going to Stock RSB back in and see what happens? Can the Strut tops wear allowing the spring to move?
HELP!!!
