I really like the look of the sport wheels but live in Nebraska and get a fair amount of snow, so I really need all wheel drive. I have a few questions:

1) Would it be possible to put the 2007 sedan sport wheels on a 2007 G35x?

2) Has anyone successfully done this?

3) If this is possible, would the ride height look ok with to the larger wheels?

Any help would be appreciated. Thanks

 

No one has done it because you are not supposed to stagger wheels on the X, thats why it isn't an option from Infiniti.
You should run the same size wheels and tires front and rear.
This has been discussed here many times.
Run some aftermarket wheels the same size all around, you have a choice of much nicer wheels also.

 

Paul, you can run 17, 18,19 or 20" wheels and tires on your X as long as the outside diameter of the tire is within a percent or two of your original size.
For example if you wanted to run 18" tires you would run 245/45R18 in place of your 225/55R17 tires since they are almost identical outside diameters, therefore your VDC and speedo will be unaffected. As I said before it is important to run the same size all around with the X.
Here is a tire size calculator that works well: Tire Calculator

 

If you want the newer 07 sedan sport wheels you would have to get all front rims for the X. On the past sedan sport wheels 05-06 they were all the same rim.

 

I may look into getting four front wheels. I know that there are aftermarket options but I guess I like the stock look. I thought I read somewhere a while back that someone was going to do this, but I can't find the post again. Thanks for the information.

 

That would look good.
I ran the 7.5 x 18" 05/06 Sport rims on my 05 X, and was very pleased with them.
