GT350R Carbon Fiber Wheels on S197?

Does anyone know if the GT350R wheels would fit on the S197 Chassis? I'm assuming the rear would fit with some wheel poke but what about the fronts? since its an 11" wheel. Anyone running a similar offset and wheel size up front?

What offset do the GT350R front wheels come in?

I can tell you that 11" wide wheels in 18" will sort of fit on a S197 if the effective offset is somewhere in the mid +30's. Tires would have to be no more than 300 mm wide as measured on 11" wide wheels, though. On 19x11, you might pick up a few more mm of actual tire width.

285/35-18 MPSS (which measure about 300 wide on 11") on 11" wide Forgestars with a little under 1.5 mm clearance to the Koni yellows. Not sure what the actual offset was any more but I don't think it was any less positive than +35. OE ride height as shown, though the car has been lowered half an inch in the suspension since with no ill effects.
