Hello, I have had my 01 gsr for about a year now and am seeing major spring sag. On the drivers side front I have 4 fingers, rear i have 3(tight). passengers side I have the same thing but a bit more loose. When you look at the car, there is a noticable sag in the back. I think it has to do with my 2 hour car trips with 2 people in the back. or maybe my heavy boom box. Has anyone else experienced this?
