Here are the specs from mine 2013 r-spec, 19s however.
Rears were the only that allowed 22 Offset without spacers
On lowering springs,I had to roll my fronts and trim the inner liner for the fronts as well. Be sure to get hubcentric spacers like those from GarageLine if you go that route to clear the larger calipers with 30 offset.
On my 2014 3.8 Ultimate auto, (stock ride hight), I went with ESR RF2's in 19X8.5 +30 front with Firehawk's in 245 35 19, and 19X9.5 +35, with 265 35 19 rears. They fit perfectly for my taste, (not quite flush but close) no spacers and no rub.
