Spring+Prismatic+Hinge results in mechanism completely breaking

[Callum_Cloth (not)]

No matter what settings I set any of my constraints to, they end up flinging when play testing or something.

For a car chassis. This is my setup for the front wheels, which I can not even continue because of this bug, or maybe a bug with my chassis.

Spring Properties

I have recreated this three times to ensure everything is connected correctly. Still, it bugs out each time I test any change or even remake it.

Turning the stiffness to 0 makes the spring have no effect. Turning the stiffness to JUST 50 makes my whole car fling itsself out of the simulation that Roblox is in. So, I’m looking for a fix or any tips.

I use prismatic constraints to keep the wheel on one axis. I use springs to simulate suspension. I use hinges to steer and turn the wheels which I haven’t even got to scripting yet because I can not figure out where I’ve gone wrong.

There are no red arrows or rings/errors within that my constraints are showing.

Debugging I’ve tried:

Disabling the spring then testing

This were the results:

---

Enabling it while testing:

Results:

Messing with properties, disabling constraints, and remaking the suspension

All have no effect.

It is narrowed down that this is caused by the springs even with the maxforce in 2000 and sitffness the same.

My car weighs 95 “RMU”.

I still need help considering I can’t create much as I have no idea what’s going on.

I’ve fixed by setting massless to false and setting custom physical off.
