I doubt I'll have any luck here but I'll try. I am looking to do a trade of my factory gm c6 5star wheels with tires and tps for 01-04 cars for your factory polished c5 z06 wheels with tires. They are stock GM polished Aluminum wheels/tires off a 2006 C6 Coupe.

The wheels are in great shape (18" in the front & 19" in the back) no curb rash anywhere.The tires are Goodyear GS-2 EMTs all around (285s in the back and 245s up front) with 7+/32nds on the outsides and 7/32nds in the middles. No patches/repairs on any of the tires.They will come with 2004 TPS for model years 2001-04. pics of the wheels on my car.
