rigidbody flying on collision

I m making a car game and when it collide to something like stone having rigidbody it starts flying in the air… I think its center of mass is gud… It does not have any prob with turning… Can anyone help ???

there are so many ways to fix that issue but what i like and do most is fixing constants in rigid body menu i think u should lock the y rotation and position ,i know it not the best way to do it but u can give it a try

thanx dude that will surely work
