I want to buy XXR 527 wheels for my 04 coupe but im a little concerned with the fitment and the tire size I should buy, if anyone could help me out I would appreciate it. I'm not looking for a stretched look on the tires btw.

Fronts: 3 options not sure which option would be best
1. 18 x 8.75 +20
2. 18 x 8.75 +35
3. 18 x 9.75 +20

Rears:
1. 18 x 9.75 +20

 

the third option for the front would probably rub if im correct

 

First XXRs are crap wheels, you would be much safer running your stock wheels.
Second, they wont even look good.

The OEM 19s with a spacer are your best bet. They are quality wheels, look good, and easy to find.
Front: 19x8 +30mm offset
Rear: 19x8.5" +33mm offset

Personally I think the ideal DD setup for the G35 to sit mostly flush without rubbing is.
Front: 19x9.5 +22 with 245/35/19
Rear: 19x10.5 +22 with 275/35/19

 

^ I agree. My car's still sitting on my stock OEM 19s and I'm pretty low, it still looks great.

 

congrats on running the lowest quality set up possible

 

A cast wheel is a cast wheel. Never had any issues with my wheels made both ways, high pressure casting vs low pressure casting. People go out and spend a fortune on specific name brand parts to say thats what they own when most of the time, its a waste of money on a daily driver. I deleted the posts since my purpose here was to help people in the future. Obviously some people think they have a purpose in life to dog on other people's cars. Which is completely fine tbh, some people need the satisfaction to go on with their day sitting behind there desk and being a keyboard warrior. That's the car culture these days. Toodles.
