Need help with wheel fitment, yes I used google already.

Those are decent sized offsets. On a 370z, 19x9.5 +20 and 19x11 +15 is nearly flush running a 245/40 and 305/30.

What size tires are you planning on running?

I thought the goal was to try and stay within factory specs of 30mm and too big of a difference would induce more understeer?

9.5's he can run wider to stay with the 305s. i'm running 265/305 on stock sport rays currently.

no the tire sizes you mentioned.

going to 60mm difference in width will most likely throw more understeer into the equation.

That's the same width for the front and a 30mm width increase for the rear.
