I'm thinking of getting some 17s for the winter and was wondering if the ones from a 03-04 G sedan will fit. I read something about their roters being smaller, so it may not clear the roters on the G sport. Thanks.

 

I test fit some 17" sport rims on my 07 and they fit the rear...barely. Front's I do not think will clear because the rotors ar larger on the front.

 

i got some 18's 350z touring edition rims that can be used as winter tires for sale if you'd like.

 

I think the sport wheels from 03/04 will fit. Someone on this board has a BBK with 13" rotors with 4 piston calipers and the sport wheels fitted over them. The 07 G35S brakes are no bigger than that. Can't speak for the non sport wheels.
