Default What does 2004.5 mean?

I keep seeing people refering to their Z's as MY2004.5...what makes it a half year? I bought mine in Aug of 04, so what does that make me?

Mine had a production date of June 2004. So I always list 2004.5. I started doing this when people were posting threads about tire feathering to determine if the 2004 / 2005's had the same problem.

Just a habit. Not sure what to call yours other than 2004.10 Seems ridiculous now that you ask.

Nissan made some changes midway through the 2004 model year, including some cosmetic changes, knee pads, suspension changes to address feathering problems, etc. Do a search on 2004.5 and you will find plenty of posts and links on the subject.

I originally found the official distinction between the two on the nissan-tech.com site. You can tell in the VIN numbers:

2004 Nissan 350Z Coupe/Roadster (Coupe VINs up to D*4T160000,E*4T060000) (Roadster VINs from D*4T102001 to D*4T110000 & from A*4T002001 to A*4T010000)

2004.5 Nissan 350Z Coupe/Roadster (Coupe VINs from D*4T160001, E*4T060001) ( Roadster VINs from D*4T110001, A*4T010001)

I spoke with Nissan about this issue and they stated any 2004 350Z with a 10/03 production date or later is considered a 2004.5

so the 2004.5 doesnt have feathering issues? I have 10k on mine and I am starting to notice a little road noise out of mine. The tires look like they still have some life out of them, but I have not inspected for feathering. The front could be warn out early due to a drift eent of two, but at a quick glance, they appear to be fine.

10K ... From the pics I have seen you would of already known.
and had it. It affects most ppl in the 6000-8000 mile range I have noticed so if you make it through there your fine.

No, the problem is not fixed on the 2004.5s. I have one and just got the tires "rotated" because of feathering at about 6500 miles.

They realigned the front end - old settings and new settings were significantly different.

i know people rotate the tires to try to combat feathering, and it sorta works for a few hundred miles, but it'll just come back.


The tires ARE directional
be careful in the rain
