SBR4 Broken Rally Coilovers?

I just wanted to know I'm making a rally version of the SBR4 for my config pack and every time it hits a large bump or gets a little bit of airtime you can see the rear suspension only gets slammed down to the ground and it makes the crash sounds and no matter what I do I can't figure out what's wrong. So if anyone knows how to fix that, pls help.




My Config Pack: https://beamng.com/resources/car_luvers-config-pack-clcp.12020/

 

this is because you could forget some lines, some comas etc

 

what?

 

So there is thing called Jbeam, and sometimes when you forget some lines, comas, and other stuff it can break and do stuff like this

 

ok but im just using the vanilla coilovers that are already in the game
