Well I just put 19's on my GTP and finally got my 3.2/XP Cam setup running and i went for a 5 minute drive at cruising speeds and literally every single bump sounded like the car was about to fall apart. It was making clanking sounds and stuff constantly unless I was on the brakes. I've heard the same sound before in the last car I owned and that was caused by a rim not being tight enough. Well, I torqued all of these to like 125ft lbs and did it twice to make sure and it sounds like all 4 are making noise. I don't understand what it could be. I measured the lugnuts it came with and the depth of the stud and it seems like they "shouldn't" be bottoming out.. that was my first guess... Anyone else had this issue? Thanks :\
