Guy 2: "Who cares about your fantasy racing? That Supra didn't have a bigger turbo. It's run what you brung!"
can be applied the other way too:
Guy 1: "That Dodge Charger SRT8 would have won against that WRX if he had used racing slicks."
Guy 2: "Who cares, he didn't race with racing slicks so he lost. It's run what you brung!"
