Love mine, 275's on the front and 305's on the back. Tire is amazing. Hooks well at the drag strip with some a little bit of heat and about 24psi. But they really shine through the twisties.
They aren't 305/35 and they aren't on z06 wheels, but i figured no one else has posted pics so these are mine.
275/40/18 555s on zr1s. Supposedly they are to get better and better the more you use them. Of course until they're bald, but you get the idea. Again they're not exactly what you're looking for, not the same tire, but the same 555 series.
