I am about buy some rims for my 06 Z (6600 miles, Enthusiast)
what is the stock offset??
and if I was to go with different offset than stock, what would be a good choice?

I'm thinking of either Volks GT-U or TE37 Time Attack... considering going 245 on the front, and about 265 on the back.

any recommendations on tire size?

 

your owners manual has your stock offset sizes -- here's a link to a 2005 manual: http://www.courtesyparts.com/nissan-...issan-350Z.pdf

here's an offset calculator: http://www.1010tires.com/WheelOffsetCalculator.asp

your questions are dependent on too many variables, and you haven't given enough information for anyone to respond. you need to spend some time researching your desired setup. best bet is to search around, see what other people have, and make a decision on what you want.

mostly, your post isn't going to get any attention because it asks questions that can't be answered.
