I just bought a 2004 350z roadster, I am looking to see what is the widest wheel or biggest offset for front and rear

 

your car has been out for 14 years, and this question has been answered a million times. check the wheel tire section to get sizes and examples

 

^^^This. Plus, you make no mention on suspension mods - Lowered? Aligned? Nor any mention of fender mods you're willing to make. And what do you mean by "biggest offset"? You have +30 now, you want to go bigger like +40 to tuck some more or what is it you want?

Just for the sake of the spoon.... 9.5/10.5 +22 with 255/275 is about what you're looking at with no mods.

 

10.5 front and 11 rear fit really well with wide tires

 

thanks for the reply.

 

no mods.. just looking for a good look on a factory setup..thanks

 

Then the numbers I quoted work just fine.

Just make sure you get the proper aspect tires for the wheel diameter to assure correct rolling diameter (height).

40 for 18s, e.g. 255/40-18, 275/40/18

35 for 19s, e.g. 255/35-19, 275/35-19

Rule of thumb: +/- 5% of aspect change required for every inch added/subtracted to wheel diameter.
