My 370z fitment.
 

Here is my 2017 370z. I am running Rays/Gramlights 57CR Nismo Clubsport wheels with Fortune Auto 500 coilovers and all of the SPL arms. My specs are as follows

Front: 18x9.5 +22
Rear 19x10.5 +12 (with 5mm spacer)

For rubber I have Bridgestone RE71R and they are 245 and 285 for size.

Overall fitment is good it rubs a tad up front but none in the rear. Super good setup for canyon cars or track cars. This setup should work for any 370/350z.
