This is my post copied from two other forums:
I'm at 90% of my next conversion. I'm not the master of rally physics so this is the reason of this thread.
I could make it by myself but if there is someone more expert than me, any help is welcome.
The two cars are not real rally cars and the mod is a "just for fun mod".
One day (a very far day) I will add other two cars to this mod but not soon.
If you think this is your job, drop me a pm.
I have few specs requirements then you will have total freedom to make the physics like you prefer.
I will start the work anyway when I will fix the last bugs and if none can help.
