Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Use a text editor to edit the "model.ini" file in the "data" folder in the game directory. Find the "[Carxx]" entry (for example, "[Car11]"), where the first number is the car model and the second number is the color. You can now edit the "Geometry", "Acceleration", "Collision", "Name", "Model", "Point", "Wheel", "Handling", "Grip", "Weight" etc. values. The recommended "Acceleration" value is "33", "Grip" is "0.0099", and "Weight" is "2.00".
