I bought some parts from this gentleman over the weekend. He's got a bunch of tires for sale, but here is his craigs add for his CCW's. Corvette set up for a C6 offset, 18x10-18x11. Had I not already purchased my set last month, I would have certainly picked these up. Thought I would post the link up. Solid price at $2,300 with tires.
