The silencers can move. You want them pinched up in the contact areas as much as possible. If they're not long enough, you may need a longer set. They work like the Chinese finger traps. When idle or pulled they're tight, but squeeze them and they make room to slide up.I lubed all contact points with silicone grease.
Do the pro kit silencers move up and down? if they do then it is possible the spring compressor could have slid it down a bit.
It's the nature of progressive (or dual rate single piece) springs. The silencer is crucial to keep the binding noise down. I would just look out for rust from the contact areas that wear away.Update: Found out that when the car was sitting and had the wheel at full lock so I can touch the spring under load it would make the noise and bind by me just wiggling it back and forth. So I assumed it was a problem with the spring itself just binding. Eibach sent me a new spring since I tried everything and the noise wouldn't go away. Installed the new spring and the noise is less frequent but still happens. At this point I don't care anymore since our other car makes way worse noises and has been completely fine for 20 years. Just annoying on a new car haha.
