YES!!! i just spent the last hour molesting the search button, and I can't seem to find out how to tell if my car is an 04 or 04.5 I would like to know if I have the revised springs or not. any help would be appreciated thanks.

 

If you have the padded knee rests, it's an 04.5.

 

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)

 

sweet thanks for all the help, thing is I have the padded knee rests and my vin ends in 100685 I'll go by the vin though, thanks a bunch.
