Entire car chassis is moving when turning

when I turn the wheels on my chassis the entire car moves, why is this happening and how can i fix this? Im using the cylindrical constraints top attachments to turn.

i have tried:
increasing/ decreasing friction
increasing the density

but to no avail. All help appreciated.

It’s just physics. When your wheels rotate, their rotational velocity impacts the connected chassis too. Because the mass small, the wheels have a larger impact on the resultant movement of your chassis.

If you’ve ever had a small RC car, you can see this same effect.

The solution is to add more mass to your car/chassis, and perhaps also mess with the friction and friction weight of both the wheels and the surface the wheels are touching.
