...interesting talk about 'feathering' fix @ Zcar.com. I hope it's true.
 

its been touched on already. new adjustable front a-arms will be on the 2005 models to get the correct alignment settings. these arms will then be a tsb for the 03-04 z's to correct tire feathering. there are some threads here that can be searched: 2005 changes, upgrades, revisions, etc.........
