No dought the Z06 is an increadable car but, the 240Z can still beat it and be a decent daily driver. Not that I'm in the low 12's or anything but, my best time of 12.9 and best MPH of 109 is not to far off the pace of the Z06 given the extra weight of the ZX and the crappy tires that I was running on. Slap a set of Corvette spec tires and a LSD that didn't have a zillion miles on it and I think a lower 12 second 1/4 could be achieved. Replace bushing, add coilovers, lighter rims and some more tuning could produce a car worthy of beating a Z06.
