First step is to read this:
Wheel Fitment 101: START HERE
Your fronts are more aggressive than your rears. A +22 would be more consistent, and in line with fairly standard 370z aftermarket sizing
Additionally, your front tire size is very wide. While a 265 on a 9.5 width wheel is within the acceptable range from the tire mfg, it is pretty “over square” from a fitment standpoint. Even Nissan itself uses a 245 width tire on a 9.5 inch tire (such as on the front of a nismo)
I would go down to a 245 front, roll your fenders, and see where you’re at
Bear in mind, however, the Z has no front camber adjustment from the factory, so your camber is whatever. At ur ally results from lowering the car and the condition of your bushings.
For full, reliable adjustment, you need new front upper control arms, the best option of which are from SPL parts
Summary:
Easy solution is swapping to a 245 tire and +22 offset wheel
Best solution is rolled fenders, adjustable arms. At that point you can run any front wheel you want.
For street, I have run a 20x11 +15 front with a 275 and currently run a 20x10 +3 with 255
For track, people regularly run 18x10.5 or 18x11 with a 275 or 285 or even 315
The Z can fit anything, if you do it right
