I might be doing something wrong, but the gears are all messed up, and (after correcting the gears) the car is all over the place!!
You tried to use a 5 year old setup file with a car that has had several tyre and suspension updates since then. That unfortunately doesn't work. Even after minor physics changes it's recommended to dump older setups and revert back to the car's new default. That's the reason there's nothing like a car setup user collection around here... But a lot of nice guys here will share their knowledge about setting up a car, should you be unsure what exactly you should change to alter a car's behaviour to better fit your liking or driving style.
