Well, I've finally sprung for new wheels and tires, and I couldn't be more pleased with the choice.
I'm running 16x7 SSR GT1's/with 225/50/WR16 Bridgestone Potenza S-03 PolePositions and the car has been transformed yet again. The tires are amazingly quiet (compared to the stock KDW's) and hold the road like crazy (going to a + size is never a bad thing, if you've got clearance). I didn't get a chance to weigh the SSR's, but simply by picking them up as compared to the stock 16" SVT wheels they feel lighter.
I'm currently running stock springs and struts, so rubbing hasn't been a problem under any driving conditions. I'll find out if I'm going to have rubbing issues in about a month with it lowered, though (I'm rebuilding my suspension with the BAT kit).
So far, I can't say enough about the combination. The extra width simply rules as does the lack of road noise with the tires. The looks/weight of the SSR's are really nice, too.
I'll try to post pics when I can.
FYI, if you are looking for SSR GT1's, you might want to purchase soon. The folks at Tire Rack have told me that the style is going to be discontinued soon (maybe only in the 16" flavor; I'm not sure, though).
