9.5 +12 is moderately aggressive in front as most people run +22

The common combo is 265/35 and 305/30 for 9.5/10.5 wheels

More to the point . . . if your suspension is stock, you are not flush. Sorta defeats the whole point of "flush"
The stock nismo is 245/40 and 285/35 and it is a little bit stretched (and thats a factory setup)
