Different prep, different weather and a different driver will all affect the 1/4 time there friend....
and as far as the aruguement that it's a Z06, that's a pretty weak one. For starters, the interior in the fifth gen is far superior to the vette, the LS3 is far superior to the LS6, the trans in the new camaro is 10x better than any previous six speed that GM has put in any of their productions cars, excpet for the ZR1 (because it is relitavelty the same). As far as handling, ride quality and feel, the camaro is far superior.
Plus, who gives a shit about .2? Honestly. The new camaro is quite amazing.
