Those are pretty damn nice. Take a photo with the sun behind you, so we can see how the tires fill the wheel wells, and I think you'll get some better reactions. And a 45 degree angle shot so we can see the lip!
They are 17X8.5 and I haven't put my eibach pro kit springs on yet. That should make them fill the wheel wells nicely. I didn't want to go over 17's because of tire cost and the fact that my right foot likes to make them smoke
I think the reason why they look 16" as many have guessed, is because sawblades are what we use as a reference many times for what a 16" looks like as far as height. But there is something I noticed: Because of the design on sawblades, the 'contour' going from edge to edge without a break through the center gives sawblades an effect that they are higher than what they really are. Not many rims have the same design, with a single long contour line to get a reference, so as a result, many other 17" rims look like they are the the same size as sawblades.
I have been humming and hawing about those wheels myself. Right now I'm leaning more towards the KZ-B's, but I'd love to see some more pics of your car! I'm tired of photoshopping the KZ-A's onto mine. ;-)
