Its not a GT3 cars, its a GT4 spec Vette....Callaway offers the GT4 car with the option for the aero parts like the front splitter and rear wing.
Yeah, based on two seconds of my own research... looks like it is based on the GT4 specs but with wings and such for another championship. Not sure if "Grand Sport" is what they call the GT4 car or if that is actually a totally new build off of the production Grand Sport.
