@J.Lupe- Is that kind of stagger beneficial in a performance aspect?
Anyway, 9.5" 0 is fine for the fronts especially if you're going to go with 20mm overs.
As for the rears, I would STRONGLY recommend a smaller width. If more grip is what you're looking for a 10.5 with meaty tires should do you fine.
But if you seriously want to run the 12", 17X12 -18 will work. Alistair ran those with fender flares + stretched tires so with 50mm overs, that should be fine.
@hellion240Sx- Go with the 16's and run 205's with the tires please, 15's on a S14 look awkward & they will fit but you will need a roll at least.
This is a 17X8.0 +30...do the math with a 0.
