I know that the ACS spring noise was issue on some of their earlier production springs that turned out to be the coils rubbing against themselves - ACS's cure was to put a sleeve on the spring, similar to a hose. But that issue has been corrected in the later production springs. I've been running my ACS springs on my car for over 2 years and haven't had any suspension issues at all. But then again I had my springs installed at a shop that does this type of work on European cars - maybe they know a few tips and tricks that they learned after the first few?
