How can I keep my car chassis from shaking while accelerating?

I have a basic chassis made of constraints, but for some reason… When I accelerate, it starts shaking, but when I reach the max speed, it acts normal. Is there anything that I can do to stop this?

Here is the car chassis:

I haven’t noticed any shaking at 150 sps for me. Are you sure its not your environment or even device?

What happens when you are at that speed? Because when I am at that speed, the car slowly turns in a random direction (It might be the fact that it’s All Wheel Drive, instead of Front Wheel Drive)

Are you using Servos or Motor6Ds for your steering?

Servos are kinda glitchy and Motor6Ds have slight issues with precision (unless you update them twice every time).

I would mess with the UpperAngle/LowerAngle of CylindricalConstraints, if you’re using those. If using regular hinge constraints, LowerAngle/UpperAngle. Set them both to the same value, restitution 0. Perfect steering.

It changes the lower limit, and upper limit, in a way that makes the wheels turn smoothly, but not CylindricalConstraints, If you want to see how I do the steering, then you can just take a look at the chassis model.

Its not something wrong with the steering (I think), because it does this:

When I am traveling in a straight line, that happens.

Don’t use servos. You can’t use enough force to keep the wheels properly straight without glitching out the physics.

Use the UpperLimit/LowerLimit method. It’s much better.

Also, I don’t know why I said that. I meant to say, that it just changes the lower limit, and upper limit, in a way that makes the wheels turn smoothly.

Have you made sure that your wheels are all aligned correctly, level and rotating on the right axis? Sorry if this is a stupid question, but you never know…

What do you mean? Everything looks just fine to me…

‘Rotating on the right axis’ = forward and back movement I mean. Maybe one of your attachments is slightly crooked? It’s a possibility!

I haven’t noticed any of the attachments being unaligned. Maybe I don’t know what I am doing?
