I just bought an 04 Nissan 350z and want to do some upgrades to it but am not sure where to begin.  I checked out computer chips, exhaust, etc and am just wondering if there is a method to the madness?  Is there a certain order that the upgrades need to be done so they complement each other better?  Any suggestions would be greatly appreciated.

I used to be a Z owner myself and kept up with the series on that car until I flipped over 9 times and well you know the rest.  

Thanks for the links.  From what I am reading, it looks like starting with suspension and tires is the way to go.  Much appreciated.
