I did the original physics of the VRX mod for rfactor (which I guess it's used by this model): this car looks great, maybe you could just make the front and rear track a little wider, this looks good to me.
FrontWheelTrack=1.6
RearWheelTrack=1.6
Also, it would be nice to have a passenger in the seat for ridealongs and the possibility to remove it to have a race day spec.
@Robin_NL 4wd sucks with realfeel plugin, disable it with ctrl+2(keypad)
Rear body wider, blue reflective sticker
Do you know much about physics engines?
I need someone to make improvements.
