Well said Kevin in the IROC the international race of campions the cars are provided by a manufacturer and they are exactly the same all you do is get in and drive and that way they test the driver or team not the ability of the team to push the envalope not that they cheat in car racing heaven forbid.... It's not boat tuning 101 it's about the abilities of the skipper and crew to take what thier given and make it go faster or out performe everyone else ....
