Installing Eibach Pro Kit today?

[SteveSkal]

I took out the rear springs and in the middle of the spring is some king of rubber cylinder looking thing, question is what is this things function and do I tranfer this over to the new springs?

Those are not needed. That's factory's way of creating the progressive springs.

 

[jEEd]

they're not needed its just another "dampener" for the progressive stock springs for when the springs touch each other when compressed cause of how slushy they are.

dont even use it you'll be fine!

good luck and i hope you like the pro kit!
