Fender Rubbing?
I have a question about a setup I'm going forward with. I know the front fenders on the 350z are already factory rolled so I'm not worried about that. On stock suspension ( for now ) will a wheel of 19 x 10.5 with a 12+ offset on the rears with 275/35/19 tires rub? I'm guessing they will due to the offset that I will need to get them rolled but I'm curious about the stock suspension. Do I need to go low per say lowering springs or coilovers for it to fit better or not rub against anything else?

If you run the stock suspension, you won't rub (or minimal rub) with the wheels and tires and offset you ask about.
If you drop the car even 0.5", you will rub if you don't roll the rear fenders.
I have a 1/2" drop with 275/40-18 on 9.5" wheels with a 15 mm offset, and I do not rub.

I'm rocking the exact measurement you're asking about on stock suspension stock height. My fenders are not rolled.
Fronts dont rub at all. Rears rub slightly when going over bumps at higher speeds or when hitting a bump mid corner. This is only during "spirited" driving. In the city or on the highway you won't rub at all. Unless the road is bumpy and you got heavy stuff in the boot. Yeah you get the picture.

All of this is academic as it all depends on the particular car and the type of components (and their amount of wear).
On suspension with bad shocks not controlling stock springs, expect more body movement as the spring motion is left to move/oscillate at their own rate with no dampening. As such, you may or may not experience any interference.
On the other end of the spectrum, take a set of fresh springs and fresh shocks, lowered an inch, you may not experience any interference because the spring motion is controlled; but you may have interference because the offset just pushes the tire out enough for intermittent or constant contact.
Confusing? Meant to be.
The point is: One cannot say, with any degree of certainty, about whether or not there will be any contact between tires and body/suspension parts with just the numbers alone. Other factors play in here and are unique to the particular car.
Spike doesn't have problems (above) while I, OTOH, started to rub slightly when I moved to +15s on a very similar height/size configuration. Might be because he's running 'Steins and I'm on Konis or slightly different rate springs or..... < could be anything >.
Suffice that the PROBABILITY of rubbing at +12 is pretty high and therefore - hating to admit it - Travlee is right.
Roll 'em and forget 'em. Or, try it out and if there's rubbing, then address it. Perfect example: my 9.5 +15s with 275s no longer rub NOR do my 10.5s +12 with 285s, now that my rears are rolled.
