I need another set of 17" wheels for my '07 G35x and don't want to spend a bunch. It's pretty tough to find something in the ~$200 range that I like, but these look promising:

OZ Hydra

They're 17x8" with 40mm offset. Correct fitment?

I'm planning to use the OE Goodyear RSA on them.

 

They should look good...

 

^+1 I think so too.

 

Using the OEM rims for winters, or what? Maybe I'm slow today but I'm not following why you need an extra set of inexpensive wheels and are not putting winters on them.

 

Yarp.

I'm using the OE wheels for winter tires, already mounted last fall.

My "original" plan was to go +2 for summer (3 season tires) and run 18" with ~45 series boots. I've decided to keep the mods to an absolute minimum since the car really doesn't do it for me. The OE tires have 90% tread left and would have been wasted if I'd gone 18".

I like to have the ability to swap winter/summer in my own garage.

 

Thanks. Is 40mm the right offset?

 

8" 40ET is fine.

 

^^^+1, they should work great.
