The test fitting was successful! I was really hoping this was the case. I bought a set of 19" HRE Flowform Monoblock FF15s for my BOSS 302 and kept them because I was told they'd fit a S550 Mustang, including the GT350. I installed Hoosier R7s on them and have really enjoyed over a couple of track weekends.
They are:
Front - 19"x10", 40mm offset; 295/30R19 tire
Rear - 19"x11', 55mm offset; 315/30R19 tire
Weight doesn't appear too far either: Approximately 1-2 lbs heavier than GT350R stock wheels in the front and approximately 4 lbs more for the rear.
