If you look at the visualizer on Subaru's Japanese site
here, you'll see that the 17 X 7.5 wheel seen on the GT trim looks to be the one we will be getting in the performance package, but it has a gunmetal finish rather than the black finish shown in the US site photos.
How difficult/expensive would it be to have the black wheels redone in that gunmetal finish (at a very high durability level)? I'm wondering if it may be less costly to use the black wheels for winters and buy a new gunmetal set for the summer tires (assuming they are made available somewhere).
