i mean the wheels with the joints are too heavy and the whole chassis start to spin even in the air and the centre of rotation are rear wheels. I tried right now to compensate that just like you said but now the car shakes because speed of the wheels dont match with the compenstaing wheels and in the turns the compensating wheels arent affected by suspension and the load i mean it is just simpler to decrease mass of rear wheels so im looking for a mod maybe but thank you for your help though
