I have a really nice set of Racing Hart wheels with Mich Pilot PS2s on them and they only have 1500 miles on them at most. They came off my 2005 G35 cpe. and I would like to put them on my 09xS sedan if possible. Does anyone know I can do this or what I would have to do to them to make this work. Sorry for the probably dumb question.

 

Assuming they are staggered size wheels (coupe), probably not a good idea to use them on your AWD sedan. If they are not staggered, then should work ok, but your speedometer will not be accurate if the tires are a different size then your stock tires.

 

It will fit right up but what is the offset and tire size?

 

Agreed. More info is needed to determine if these wheel would fit properly. Offset, tire size, wheel size, etc. You can run a staggered setup with AWD, but careful attention needs to be made in regards to overall diameter of the tires.
