Only problem is now my car VIBRATES/RATTLES very noticeably at 60mph ~2250 rpm. Im gonna try the wine cork method mentioned earlier but god damn its annoying.

Think it could be the install? Im gonna try and take it to a shop next week to see if they can figure anything out
If its Vibrating try adjusting the clamps and be sure its not touching anything especially the bumper. We have noticed some shift after installation and need to be re-adjusted.
