I appreciate your analysis, the oversteer can be the rear suspension because the car has grip in tyres and aerodinamic in the physics (check out the parameters with the debug apps of kunos of the aerodynamic and tyres grip), so i guess that is the rear suspension, i will revise it for to correct the oversteer.
i can't see the image on the rear bug, so i can't see it. please, put it right.
The tires form in the centre is not curve as a real tire, i saw this a lot time ago but i leaved it for later, now i will change it and i will put the tyre form with the curve in the center as real tyre and iwill try to make more detail in the tyres for to be more realistic
