Please say yes!!!!???

Don't think its possible without rubbing..

depends on camber and ride height, Simpateko had 18x11 GT3 wheels on a NB and it looked great, different brand tires probably paly into it also. Not really advised to put 11x18s on a NB FWIW.

I have 10.5" rears on mine. It's tight.

Yes, 18 x 11s will fit with the correct offset and a 285/30/18 tire. No rubbing at RoW ride height.

The technical answer is "yes you can" but like any answer it is qualified...you "can" fit 11" rims if you have the right offsets and depending on your tire's width and height of your car. Leaving aside the issue of offsets, there are three widths you need to be concerned with...the rim width, the tire's tread width and the tire's sidewall width (i.e. section width)...whether a particular rim with a particular offset will fit will depend on all three of these as well as how low the car is.

For example, if you currently run a 265 on a 10" ET65 rim and switch to using the same tire on an 11" rim with the same ET65 offset, it is true that the rim width has increased by 1/2" on both the inboard and outboard sides (i.e. 1" in total) while the treadwidth itself has not (it still remains 265)...however but what you need to consider is that the overall tire section width has increased by an amount that is less than 1" but more than zero (it's actually more like 1/4" per side rather than 1/2" on a 265 mounted on a 10" rim). When you mount a tire onto a wider rim what happens is that the tread width stays the same but the shoulders get more rounded and sidewalls are pulled out since the beads are stretched to the full width of the rim. In this example a 265 tire is already pretty stretched out if mounted on a 10" rim so if it is then mounted on an 11" rim even it is stretched even further out the incremental increase is not that large, and if the tire had fit previously then it will also likely fit using the 11" with no significant issues. On the other hand say if you were running a 305 on a 10" rim and then moved to an 11", the width at the sidewall/shoulder will increase significantly (since a 305 is not stretched at all when mounted on a 10" rim) and if your car is fairly low, it will likely rub.

Not sure if this is clear but if you draw a picture you'll see what I mean.( BTW the car in the sig pic below is running 11" and 9" rims.)

Thanks all and especially David for the input.
What I'm looking at is:
Front:
54mm offset/ 9 " wheel
Back:
65mm offset/ 11" wheel

My car has stock ride height

Are these offsets viable for this project?
Will spacers help or actually make it worse?
Will I need to do "fender rolling"?

I am trying to keep the car stock, so if it will need modifications, I rather stay away.

Thank you guys for all the info so far and whatever you can pitch in after the latest update.
