For you bros with the 2003 feathering issue, I saw this post on a chat with Motorweek's mechanic Pat Goss:

Falls Church, Va.: Mr. Goss, Thanks for the chat. Submitting early, I've heard numerous complaints in regards to the front tires wearing unevenly on the 2003 Nissan 350Zs. Do you know what could be causing this imperfection, other than the obvious (alignment)? I hear the temporary solution is to flip the tires but, this only last about 10k. Thanks again.

Pat Goss: Did your car go back for the recall? Our first test car at MotorWeek went through its front tires in a matter of a couple of months. Nissan told us this was a common problem and performed the recall which involves changing the alignment settings.

 

Old news my Z brother. Welcome to yesturweeks.

 

Just passing on some info, Goss is local and does a chat at the Wash. Post every week, but I am aware Nissan is still dodging the issue.

 

Had mine aligned after the fronts were just ruined and haven't had the slightest problem in more than a year now.
