This will generate a lot of mixed feelings, but we knew people were going to ask about the ND wheels on NA/NB, so we took a look at it.
***This is just to satisfy curiosity, we don't recommend 17" on the NA or NB***
17x9 4x100 6UL with 235/40/17, no spacers:
With a flare in the rear and lots of stretch to the front fender on this car, we can't make any conclusions about clearance with standard fenders. Looking at it, I'd expect it to need a strong roll and pull to fit these under stock fenders.
Inner clearance:
Front clears everything without a wheel spacer at "normal"steering angles that you would see in highway or track driving. Rubs on my 3" brake duct hoses in the last 1/2" to full lock. A steering angle stop could prevent this at the cost of parking lot turning radius.
Suspension travel is the killer here. This tire is 1.3" taller than a 225/45/15 and 1.8" taller than 245/40/15. That means less bump travel before tire hits the tub. At my ride height in the pics, there is ~1.325" of bump travel available in the front. A big spacer on the shock shaft would be mandatory to engage the bumpstop earlier and limit travel.
Front inner clearance in photo below. :
Forgot to snap a picture of the rear, but the wheel/tire clears everything on the inside juuuuust barely. Bump travel looks OK in the rear, but if you only limited shock travel in the front, you'd be in for some funky handling characteristics.

<p>Ha. Maybe for my next set... already pre-ordered 
Picked up the x9's direct from 949, and the X8's through JR.</p><p>Silly me though... Didn't order enough lugnuts or valves
