With the FSVT 49mm offset, I'd run a 5mm spacer and perhaps fit on 235/40/17's to fill the wheel well out. 5mm is max depending on the thickness of the wheel mounting flange and using the stock lugs. You need at least 3/4 to a full set of threads through the nut to stay safe. With my rims (Superior Scoundrels 17x7) I had a 42 mm offset, running 235/40/17's and had to roll the lip. I have 8-10mm clearance from the strut and would like to be a bit closer. The FSVT rims with spacer would be 2mm closer and fit perfect with minor clearancing needed on the rear fender lips.
