i am having intermittent noise when going over sharp bumps after eibach and koni yellow put in...It looks like the coils are really close to one another and might hit each other under when go over big bumps...anyone else have this problem?? probably gonna try to warp radiator hose around these coils to see if the noise still exist

 

A section of the rear springs should have a clear hose on already. Did you install the rubber plates that go between the spring seats and the springs?

On side note:
I believe Eibach Prokits are not true progressive. The springs are progressively wound, but doesn't have progressive spring rate. The dead coils are pretty much touching each other when they are loaded.

When the springs are installed on the car, the whole suspension setup becomes progressive because of the bump stops. That's why Eibach and a lot of other spring manufacturers don't recommend cutting the bump stops.

 

rubber piece between the springs and the spring seats??? yeah i do have the clear plastic cover....i am not sure it is it the spring hitting each other...sounds like it but very minor......u mean at the bottom of the springs???? yeah....everything look fine but i might have to retorgue all the bolts...

 

There's a round rubber/plastic, if you will, part that sits between the OEM spring and shock. These rubber isolators clip to the shock boots. I don't have the pic, but if you see your springs are sitting directly on top of the Koni seats, you don't have those isolators.

 

I'm experiencing the same noise that you had with your Eibach pro Kit. Did you ever get it fixed?
