Solved shaky rear suspension

My rear suspension is very shaky at low speeds

 

The rear end shakes a little bit with it as well

 

this isnt very helpful if you dont post any pictures of the car/jbeam

 

You probably decreased the spring height if so, try increasing the spring height. Hope it helps

 

And could you please show me how to make it less stiff? Changing some numbers in the suspension file might do something....

I did decrease the beamprecompression, but raising it would defy my reasons to why I lowered it in the first place. I originally planned to make it the same level as the front suspension

 

Here is a video
