My 2004 g35 has sport tuned suspention. I have been searching so many of web sites and past posts that were discussed about wheel size. However, I have no idea of it because there is too much information and I am really confused what wheel size I should get.
what wheel size is the best for my g?

 

For the G35 Sedan, going aftermarket, I would def. recommend 19s following a nice drop.

 

I saw lots of pics of g with 19s and they looked great. However, i was told that if i get 19s, i should give up my g's performance. is it true?

 

nothing you would notice

 

can you give me detail info about 19s such as offset, tire size? actually, i really hate to get rims out of fender lines. Thanks

 

19x8.5, +38 offset, 245/40/19.

 

Offset depends on what kind of width you are going for. For the front - anywhere from +35 to +43, rear from +40 to +50 will keep the wheel inside. I have a staggered fit +35 245/35/19 front +48 275/35/19 rear.
