Greetings

I'm trying to find the difference between the years of the 370z nismo from 2010 through 2016
I found that the ratings for 2010 are better than the ones that follow.

I wonder if there's difference in the chassis itself.
Internal motor parts
electrical technologies and cabling
production materials
overall performance
