dont know if this is going to help or not, but those look like C6 Z06 wheels, IMO... and those Z06 wheels look really good on F-bodies... I do not usually condone the use of Corvette wheels on an f-body, because 1.) its been done a million times, and 2.) I think Corvette wheels are Corvette wheels and Camaro wheels are Camaro wheels, and never the twain shall meet... but for some reason, C6 Z06 wheels look pimp on LS1 Camaros
here are the wheels I am talking about... available for most aftermarket applications.
