Regardless of the tire size I would recommend 25mm Rear Spacers and 20mm front spacers for a more aggressive look or at the minimum 20mm rear and 15mm front for the 370 to have a nice aggressive stance. The wheels just don't look as good without the spacers...

But thats not really what your thread was about...

IMO you can go with 285's in the rear and have zero concern about too much under steer added while keeping your factory 245's up front... I am pretty sure the Nismo comes with 245s in the front and 285's in the rear... The Sport Package Z comes with 275's.... So my point being, the " superior " handling Nismo 370 comes with 285's right out of the gate and I have never heard a single nismo owner complain of too much understeer...

So again, IMO, I say get the 285's along with 25mm rear spacers and 20mm front spacers and you will give your car a much more aggressive look than factory...

hope that helps !
