I just got my car lowered about a week ago (last saturday). Ever since i got it, i noticed that whenever i go over some bumps, it sounds like something is rattling in the back of my car. It almost sounds like something is loose. It comes mainly from the rear right, but when the bump is hard enough, it comes from the rear left. Does anyone know whats wrong? Something not get tigtened all the way? My set up is H&R Sport Springs/Tokico Illumina. thanks.
