YouTube - ZR1 Nurburgring Official 7:26.4 Record Corvette Run
From the wheel movement and car movements the ZR1 looks to be far more stable and composed than both the Zonda and GTR (low and high speed). I guess thats proof that the much hyped about Magnaride suspension works. Even with the headwind its also interesting to note that the 638hp ZR1 was only able to reach 179mph on the long straight, whereas the 480hp GTR reached 180mph.
I would say that with a better driver *cough* C6R driver *cough* they would have a far better time, at times I feel that Jim Mero was taking some very conservative lines. It's also funny watching him throw his hands up in the air when he does something wrong like taking a very wide line or hitting the limiter.
