This Camaro was built 2 years ago....before the Z28 existed. Chevrolet had to homologate the Camaro to enter the GT3 FIA class racing and they did it several years ago. Basically the same way the Corvette Z06R is homologated for the same GT3 class. The Vette has won many FIA races world wide [ built by Callaway ] . So far the Camaro has not been competitive in GT3.
