[Official] 370z wheel fitment guide (pics/specs) only
He is running 20x10.5 +20 with a 255/35 tire. Eibach springs and no fender mods.
Your wheel is only 2mm more inboard, you should be fine (assuming it has a face design that clears brakes. betting you're looking at a Te37 variant?)
Another tire size that could work with that is 275/30 but may require camber/fender roll depending on height
I am running 20x11 +15 with a 275/30. 3 deg camber and fender rolled. No rubbing.
