Finally, I got my GC suspension (GC coilover+konis sport+GC rear shock mount)intalled...again with all the right parts, I hope. I went for a test drive and my first impression is rattle noise on the front and squeaky noise on right rear. I think rattling noise on the front is due to the adjustable sleeves did not fit tight on the strut. GC did send me some O-ring to fit between them but it was too thick. I talk with Tony at GC and he insisted me to use masking tape around the strut so the adjustable sleeves will slide on tight. I did that and it still making noise. Squeaky noise on the rear sound like when the shock compressed, it make the noise. Anyone have any solutions for my problems please post. I just don't want to live with these noises and if there is no solution, I may get rid of the GC coilover and get something like H&R sport springs. Thanks
