I found the ZR1 to be somewhat disappointing. All that power and they aren't any faster than a $30000 cheaper Z06. A month or two ago I went looking for some blazing fast stock and bolt-on 1/4 times just out of curiosity, to see what they could do. I knew that the Z06s had hit 10's stock with absolute perfect conditions and drivers, so I figured mid-low 10's for the ZR1. I ended up on a Corvette forum and started reading and it turns out that even with some of those same badass drivers no ZR1 had run faster than a Z06 stock for stock. The Z06s even trapped faster. Never found out exactly why, but I think the car couldn't get the extra power down through the fancy suspension, along with the extra weight. Even the bolt-on cars were struggling in the mid 10's for the most part.
