I've been interested in these wheels since I saw them on TireRack several months ago. I'm a big fan of the y-spoke style: Bayern Mesh, CSL reps, Breyton GTS, etc.
I searched and it doesn't look like anyone has put GT1's on their 1'er yet, but this guy has them on his VW GTI:

I think they'd look pretty good on our cars.
