I have an 04 350z enthusiast and im about to get new rims. i want to get wider wheels than the stock ones.
Im looking at 18x10 for the back and 18x 9 for the front. or do 18x9 or both front and back. do i need to get spacers? or would these wheels fit okay with out them? any other suggestions for wheel sizes would be appreciated. also wondering what size tires i should get? my car is not lowered pretty much all stock. It is also my daily driver. any tips and suggestions would be much appreciated thanks.

im trying to avoid rolling or flaring my fenders. if 18x10" on front and back work that would be ideal. just need to know if that will work with and then what tire size would be recomended? thanks

Depends on the offset. The 06-08 Grand Touring (like mine) and the 07-08 Nismo came with 18x9 front and 19x10 from the factory and will fit any 03-08 350z.These wheels are both +30mm offset, honestly not a lot of choices out there in the correct offset but spacers can be used to make more common offsets work. As for tires 285's will fit on all four wheels without rubbing at stock height, it's very tight on the front. No rolling, no flaring it just fits. Now if you lower the car all bets are off. Narrowing tires will give you a bit more play room but I'm an autocrosser and I always want as much tire as I can fit.

I may want to lower my car in the future so i do want to leave some room to do so. not trying to be a carpet sweeper or anything. got too many speed bumps and pot holes around for that shenanigans. i currently have the stock 17" rims i believe the front is 8" with 225/50 size tires and the back is on an 8.5 in with 235/50. I have decided to go with integram konig rims http://konigwheels.com/wheels/flow-form ... /integram/
i want to do 18" rims for sure. so if i did 18x10 with 265 in the front and the 275 in the back would that still give me enough room lower it a bit? this is really my first time upgrading my wheels so i dont really know how to picture what the different tire sizes will look like

You'll want the +27 front and the +25 rear. Should clean stock, if you lower you might need camber arms to get the needed clearance but I think it'll still clean unless you go crazy low.

ill give that a shot thanks for the help ill post pics when its all said and done. might change the rim color to black though.

looks like i might have to go 18x9 front and 18x10 back if i want to get that particular offset according the specs and sizing from this sight. http://konigwheels.com/wheels/flow-form ... /integram/

yup, 18x10 fronts usually require a bit of rolling.
