How to fix cart wobbling

I’m making a cart ride like game with the cart being controlled with W and S (forwards and backwards). But when stopping or switching directions the cart weirdly bobs up and down.
Video of it happening:

Also how could i make the cart accelerate slower and have a higher max speed.
Thanks for reading.

That looks intentional. Are there any rope or spring constraints? Change them to welds.

It’s not. And there are no rope constraints, but there are spring constraints for suspension tough. But if i change it to welds, then it wont even go over the track properly.

That’s why we do these things, to figure out why the constraint is in there in the first place. In this case, to keep it on the track.

I see a couple factors you could tweek and reduce the bounce. MaxLength, and stiffness. You will have to experiment within your own build to see what you can get away with.

Read up on the properties of SpringConstraints in this link.

0 Damping doesn’t act like a shock absorber, it’s just a spring.

I never use a MaxForce of inf, and since your Stiffness is 0 then it means there is no restriction to the spring’s movement.
