The better test is to bring 2 normal production customer cars of each model, run them all on same sunny day to neutralize weather effects on track surface and average out the runs . Letting Ferrari supply the car for essentially a PR event ( to prop owner's egos ) to " prove" the naysayers are wrong about the Enzo's possible inferiority on the NS vs the C-GT is bogus , IMO , esp on a factory Enzo supplied long after end of production - it's gonna be so " prepped " and probably not like any customer car in it's motor ECU , traction control settings and programming for susp mgmt , so what's the point ?
