He has actually been beat by another guy on Corvetteforum named Jamie Furman who ran a 10.83@130.05 MPH on drag radials and a 10.98@128.9 on stock tires, also bone stock other wise. He is the only known one to get into the 10s on stock tires. This is form the Z06 which the offical numbers from GM are 11.7@124. Now the ZR1's offical number are 11.3@131. Just think what the times for the stock ZR1 is going to be when it gets on a good track, with good weather, and a great driver. 10s easy on stock tires and who knows how low into the tens on drag radials. I think the only problem will be getting drag radials for the wheel size.
