Specifics are not important. All you have to do is take completely stock car. Change the chassis, the body, and the engine to whatever you want. You can make the tires what ever you want, as well. You just have to keep all the other parts stock. Stock suspension, stock brakes, etc. You can take those stock parts from any stock car, in the game.
For example:
Ford GT40 Polophony Digital Special
I started with a Mustang Cobra R
Brakes: TVR Speed 12
Brake Controller: none
Chassis: GT40
Engine: GT40
Drivetrain: GT40
Transmission: GT40 (normal; non race)
Suspension: GT40 (normal; non race)
LSD: none
Tires: any
Weight Reduction : none
Body & Downforce: GT40
Polish, balance, etc.: none
This is just an example, you can do all sorts of combos. You can also edit many of the specs of the car, in the *.ini file. Just as long as the parts are kept stock, you can edit the values. Also, to have a real advantage over the computer, use line 440 or the power multiplier. The computer does not recognize this as a "modification".
