alright, I've got some 350z 18's arriving today and got to thinking about lugnuts...so I did a search and didn't come up with much. Will I need to buy new lug nuts? If so where can I buy them and also what is with hubcentric rings...what do they do and do I need them? Thanks for your help.

 

You don't need new lug nuts. Maxima hub size is 66.1. If the wheels that you're installing have different hub size, ex. 72, then you'll need hubcentric rings otherwise there'll be vibration and your steering wheel will shake. However, if the hub size is close to spec, ex. 66.5, then you should be fine. Hubcentric rings are available at Dicount Tire - $15 for a set of 4.
