I guess this can be used without the original mod, as it contains most of the changes:
-Fixed weight for all cars (based on real life cars)
-Improved weight distribuction for all cars
-Improved external camera for all cars
-Improved internal camera for all cars
-Improved driver position for all cars
-Improved tachometer and speedometer for all cars (still not perfect)
-Improved handling for all cars
-Improved steering help for all cars
-Improved bots handling
And the rest of the changes would be overwritten by other useful mods anyway.
