Very good job..I have found that most of this noise occurs in cars with the Sport Package because of the larger tires..
Anyway .. all is well now and I might add that the guy that fixed it said he has driven many many exotic cars because a very high end dealer has him do work for him and he told me this Z compares favorably with Porsches costing 90K!!

The key is the upper area of the hatch and the doors... I could still do more but right now I am just going to relax and enjoy the car..

and one other thing to all the guys on this post..this is totally off topic but I will say it anyway.. get yourself a PSA test.. Prostate Specific Androgen.. An incredible One in seven to one in three males will find they have prostate cancer.. I figured it would never happen to me but it has..but I am lucky because i detected it early and am a survivor..if I had waited until I had symptoms I would be dead after two years of misery.. It was when I got this disease and was lucky enough to get it treated early that I said "F" it!! I am buying this car. NOW and that is the "rest of the story!" ..Perhaps I can save just one life by posting this...Spread the word..
