Hi There,

I am facing a problem with my car physics. I applied suspension, pacejka tyre forces and torques and i feel that i did it very well. I am using improved Euler integration for computation. That is
forces();
K1 = vOld*dt
forces();
K2 = vOld*dt;
vNew += (K1+K2)/2............(Just a Hint)

But Longitudinal traction torque applied to chassis shoots the car up as you can see in the video....Here is link for that

What could be the possible solution for it...Should i increase the gravity pull or increase the suspension force...Any idea on it....??........:)

From the video, it looks like the car (chassis) mass is too small?

When I increased the weight from 1200 kg to 12000 kg, the car moves gud horizontally but when i turn my car it overturns....:(

It works good when i drive slowly. Pressing and releasing the throttle. Nut on full acceleration it overturns. :(

where's the centre of mass of your car? you should place it lower, near the street.
