i had a question wondering if eibach sportline springs make noises, because tein stechs come with that rubber thing to prevent noise, and eibachs dont. thanks.

 

My H&R springs never made any noise that I can remember, and they didn't have any rubber on the coils. But if you get the Eibachs and they do make noise, you can buy the rubber coil isolator things from many different places.

 

My GC extended upper mounts (top hats) came with what seems to be a polyurethane ring, to go between the spring and mount, which makes noise as the spring twists during compression. This should be about the only sound from springs, unless you are somehow going into coil bind.
